Cappadocia (/kæpəˈdoʊʃəˌ -ˈdoʊkiə/; Turkish: Kapadokya, from Greek: Καππαδοκία) is a historical region in Central Anatolia region, Turkey. It is largely in the provinces of Nevşehir, Kayseri, Aksaray, Kırşehir, Sivas and Niğde. Today, the touristic Cappadocia Region is located in Nevşehir province.

According to Herodotus, in the time of the Ionian Revolt (499 BC), the Cappadocians were reported as occupying a region from the Taurus Mountains to the vicinity of the Euxine (Black Sea).^[1] Cappadocia, in this sense, was bounded in the south by the chain of mountains that separate it from Cilicia, to the east by the upper Euphrates, to the north by the Pontus, and to the west by Lycaonia and eastern Galatia.^[2]

The name, traditionally used in Christian sources throughout history, continues in use as an international tourism concept to define a region of exceptional natural wonders, in particular characterized by fairy chimneys,^[3] in addition to its religious heritage of being a centre of early Christian learning, evidenced by hundreds of churches and monasteries (such as those of Göreme and Ihlara), as well as underground cities that were dug to offer protection during periods of persecution.^[4][5]

The earliest record of the name of Cappadocia (/kæpəˈdoʊʃəˌ -ˈdoʊkiə/; Turkish: Kapadokya; Ancient Greek: Καππαδοκία, romanized: Kappadokía, Classical Syriac: ܩܦܘܕܩܝܐ, romanized: Kəp̄uḏoqyā, from Old Persian: 𐎣𐎫𐎱𐎬𐎢𐎣 Katpatuka; Hittite: 𒅗𒋫𒁉𒁕, romanized: Katapeda; Armenian: Կապադովկիա,, romanized: Kapadovkia) dates from the late sixth century BC, when it appears in the trilingual inscriptions of two early Achaemenid emperors, Darius the Great and Xerxes I, as one of the countries (Old Persian dahyu-). In these lists of countries, the Old Persian name is Katpatuka. It was proposed that Kat-patuka came from the Luwian language, meaning "Low Country".^[6]

Subsequent research suggests that the adverb katta meaning 'down, below' is exclusively Hittite, while its Luwian equivalent is zanta.^[7] Therefore, the recent modification of this proposal operates with the Hittite katta peda-, literally "place below" as a starting point for the development of the toponym Cappadocia.^[8]

The earlier derivation from Iranian Hu-apa-dahyu 'Land of good horses' can hardly be reconciled with the phonetic shape of Kat-patuka. Several other etymologies have also been offered in the past.^[9]

Herodotus wrote that the name of the Cappadocians was applied to them by the Persians, while they were termed by the Greeks "White Syrians" (Leucosyri),^[10] who were most probably descendants of the Hittites.^[11] One of the Cappadocian tribes he mentions is the Moschoi, associated by Flavius Josephus with the biblical figure Meshech, son of Japheth: "and the Mosocheni were founded by Mosoch; now they are Cappadocians". AotJ I:6.^{[citation needed]}

Cappadocia appears in the biblical account given in the book of Acts 2:9. The Cappadocians were named as one group (among "Parthians, Medes and Elamites; residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia")^[12] hearing the Gospel account from Galileans in their own language on the day of Pentecost shortly after the resurrection of Jesus Christ. Acts 2:5 states "Now there were staying in Jerusalem God-fearing Jews from every nation under heaven," seeming to suggest that some of the Cappadocians were Jews, or part of the diaspora of Jews present in Jerusalem at the time.^[12]

The region is mentioned in the Jewish Mishnah, in Ketubot 13:11, and in several places in the Talmud, including Yevamot 121a, Hullin 47b.^[13]

Under the later kings of the Persian Empire, the Cappadocians were divided into two satrapies, or governments, with one comprising the central and inland portion, to which the name of Cappadocia continued to be applied by Greek geographers, while the other was called Pontus. This division had already come about before the time of Xenophon. As after the fall of the Persian government the two provinces continued to be separate, the distinction was perpetuated, and the name Cappadocia came to be restricted to the inland province (sometimes called Great Cappadocia), which alone will be the focus of this article.^[14]

The kingdom of Cappadocia still existed in the time of Strabo (c. 64 BC – c. AD 24) as a nominally independent state. Cilicia was the name given to the district in which Caesarea, the capital of the whole country, was situated. The only two cities of Cappadocia considered by Strabo to deserve that appellation were Caesarea (originally known as Mazaca) and Tyana, not far from the foot of the Taurus.^[15]

Cappadocia lies in central Anatolia, in the heartland of what is now Turkey. The relief consists of a high plateau over 1,000 m in altitude that is pierced by volcanic peaks, with Mount Erciyes (ancient Argaeus) near Kayseri (ancient Caesarea) being the tallest at 3,916 m. The boundaries of historical Cappadocia are vague, particularly towards the west.^[16]

To the south, the Taurus Mountains form the boundary with Cilicia and separate Cappadocia from the Mediterranean Sea. To the west, Cappadocia is bounded by the historical regions of Lycaonia to the southwest, and Galatia to the northwest. Due to its inland location and high altitude, Cappadocia has a markedly continental climate, with hot dry summers and cold snowy winters.^[17] Rainfall is sparse and the region is largely semi-arid.^{[citation needed]}

Cappadocia contained the source of the Sarus and Pyramus rivers, and the middle course of the Halys river, and the tributary of the Euphrates, later called Tokhma Su. As no one of these rivers was navigable or served to fertilize the lands along its course, none has much importance in the history of the province.^[15]

Ignimbrites of Miocene age are present within the area. The distinctive landscape of Cappadocia was formed through the erosion of thick volcanic deposits created by ancient eruptions of Mount Erciyes, Mount Hasan, and Göllüdağ. Over millions of years, wind and water erosion shaped these soft volcanic rocks into the region’s characteristic fairy chimneys and rock formations.

Prominent rock formations such as Ortahisar and Uçhisar are composed of harder volcanic rock layers, which were more resistant to erosion than the surrounding softer deposits. As a result, these formations remained elevated over time and were later adapted for the construction of rock-cut castles and settlements.

In respect of the 'voluminous eruption deposits in a fluvio-lacustrine sequence with 'fairy-chimney' development produced by uplift and erosion', the International Union of Geological Sciences (IUGS) included 'The Miocene Cappadocian ignimbrites sequence' in its assemblage of 100 'geological heritage sites' around the world in a listing published in October 2022. The organisation defines an IUGS Geological Heritage Site as 'a key place with geological elements and/or processes of international scientific relevance, used as a reference, and/or with a substantial contribution to the development of geological sciences through history.'^[18]

The location of Achaemenid Cappadocia.^[19]

Cappadocia was known as Hatti in the late Bronze Age, and was the homeland of the Hittite power centred at Hattusa. After the fall of the Hittite Empire, with the decline of the Syro-Cappadocians (Mushki) after their defeat by the Lydian king Croesus in the 6th century BC, Cappadocia was ruled by a sort of feudal aristocracy, dwelling in strong castles and keeping the peasants in a servile condition, which later made them apt to foreign slavery. It was included in the third Persian satrapy in the division established by Darius but continued to be governed by rulers of its own, none apparently supreme over the whole country and all more or less tributaries of the Great King.^[15][20]

After ending the Persian Empire, Alexander the Great tried to rule the area through one of his military commanders. But Ariarathes, previously satrap of the region, declared himself king of the Cappadocians. As Ariarathes I (332–322 BC), he was a successful ruler, and he extended the borders of the Cappadocian Kingdom as far as to the Black Sea. The kingdom of Cappadocia lived in peace until the death of Alexander.^[15]

The previous empire was then divided into many parts, and Cappadocia fell to Eumenes. His claims were made good in 322 BC by the regent Perdiccas, who crucified Ariarathes; but in the dissensions which brought about Eumenes's death, Ariarathes II, the adopted son of Ariarathes I, recovered his inheritance and left it to a line of successors, who mostly bore the name of the founder of the dynasty.^[15]

Persian colonists in the Cappadocian kingdom, cut off from their co-religionists in Iran proper, continued to practice Zoroastrianism. Strabo, observing them in the first century BC, records (XV.3.15) that these "fire kindlers" possessed many "holy places of the Persian Gods", as well as fire temples.^[21]

Strabo relates, were "noteworthy enclosures; and in their midst there is an altar, on which there is a large quantity of ashes and where the magi keep the fire ever burning."^[21] According to Strabo, who wrote during the time of Augustus (r. 27 BC – AD 14), almost three hundred years after the fall of the Achaemenid Persian Empire, there remained only traces of Persians in western Asia Minor; however, he considered Cappadocia "almost a living part of Persia".^[22]

Under Ariarathes IV, Cappadocia came into relations with Rome, first as a foe espousing the cause of Antiochus the Great, then as an ally against Perseus of Macedon. The kings henceforward threw in their lot with the Republic as against the Seleucids, to whom they had been from time to time tributary. Ariarathes V marched with the Roman proconsul Publius Licinius Crassus Dives Mucianus against Aristonicus, a claimant to the throne of Pergamon, and their forces were annihilated (130 BC). The imbroglio which followed his death ultimately led to interference by the rising power of Pontus and the intrigues and wars which ended in the failure of the dynasty.^[15][23]

The Cappadocians, supported by Rome against Mithridates VI of Pontus, elected a native lord, Ariobarzanes, to succeed (93 BC). In the same year, Armenian troops under Tigranes the Great entered Cappadocia, dethroned king Ariobarzanes and crowned Gordios as the new client-king of Cappadocia, creating a buffer zone against the encroaching Romans. When Rome deposed the Pontic and Armenian kings, the rule of Ariobarzanes was established (63 BC).^[24]

In Caesar's civil war, Cappadocia was first for Pompey, then for Caesar, then for Antony, and finally, Octavian. The Ariobarzanes dynasty came to an end, a Cappadocian nobleman Archelaus was given the throne, by favour first of Antony and then of Octavian, and maintained tributary independence until AD 17, when the emperor Tiberius, whom he had angered, summoned him to Rome and reduced Cappadocia to a Roman province.^[24]

In 70 AD, Vespasian joined Armenia Minor to Cappadocia, and made the combined province a frontier bulwark. It remained, under various provincial redistributions, part of the Eastern Empire for centuries.^[25] In 314, Cappadocia was the largest province of the Roman Empire, and was part of the Diocese of Pontus.^[26] In 371, the western part of the Cappadocia province was divided into Cappadocia Prima, with its capital at Caesarea (modern-day Kayseri); and Cappadocia Secunda, with its capital at Tyana.^[26]

By 386, the region to the east of Caesarea had become part of Armenia Secunda, while the northeast had become part of Armenia Prima.^[26] Cappadocia largely consisted of major estates, owned by the Roman emperors or wealthy local families.^[26] The Cappadocian provinces became more important in the latter part of the 4th century, as the Romans were involved with the Sasanian Empire over control of Mesopotamia and "Armenia beyond the Euphrates".^[26]

Cappadocia, now well into the Roman era, still retained a significant Iranian character; Stephen Mitchell notes that "many inhabitants of Cappadocia were of Persian descent and Iranian fire worship is attested as late as 465"^[26] and the area also contained a sizeable Armenian population since antiquity.^[27] For most of the Byzantine era it remained relatively undisturbed by the conflicts in the area with the Sasanian Empire, but the Persian Wars of the 610s and 620s placed Cappadocia on the frontline for the first time since the first century.^[28]

The exact date of arrival of Christianity in uncertain, but latest from the third century it was firmly established in society and the Church was fully developed.^[29] The Cappadocian Fathers of the 4th century were integral to much of early Christian philosophy. It produced, among other people, John of Cappadocia, Patriarch of Constantinople from 517 to 520, and Macrina, an early champion of women's monasticism.^[30] The region suffered famine in 368 described as "the most severe ever remembered" by Gregory of Nazianzus:

The city was in distress and there was no source of assistance [...] The hardest part of all such distress is the insensibility and insatiability of those who possess supplies [...] Such are the buyers and sellers of corn [...] by his word and advice [Basil's] open the stores of those who possessed them, and so, according to the Scripture, dealt food to the hungry and satisfied the poor with bread [...] He gathered together the victims of the famine [...] and obtaining contributions of all sorts of food which can relieve famine, set before them basins of soup and such meat as was found preserved among us, on which the poor live [...] Such was our young furnisher of corn, and second Joseph [...] [But unlike Joseph, Basil's] services were gratuitous and his succour of the famine gained no profit, having only one object, to win kindly feelings by kindly treatment, and to gain by his rations of corn the heavenly blessings.^[31]

This is similar to another account by Gregory of Nyssa that Basil "ungrudgingly spent upon the poor his patrimony even before he was a priest, and most of all in the time of the famine, during which [Basil] was a ruler of the Church, though still a priest in the rank of presbyters; and afterwards did not hoard even what remained to him".^[31] Basil also famously constructed near Caeserea the Basileias, a vast complex with hospices for sick, churches, quarters for travellers and facilities for doctors and nurses.^[32]

The Arrival of Muslim Arab armies in the mid-seventh century resulted in the breakdown of civil and military order of the Eastern provinces and a colossal displacement of population.^[28] Cappdocia became a border region of the Byzantine Empire, frequently raided by the Caliphate. From the 7th century, Cappadocia was divided between the Anatolic and Armeniac themes.^[28] The frontier zone between Caeserea (Kayseri) and Melitene became a no-man's land, in which the akritai and ghazis fought each other and which is remembered in the epic Digenes Akritas.^[33] The warfare, consisting of the yearly razzias as well as major campaigns took a heavy toll on the cities and villages, especially on the favourite Arab lines of march.^[34]

Cappadocia contains several underground cities (see Kaymaklı Underground City), many of which were dug by Christians to provide protection during the Arab raids and periods of persecution.^[5] The underground cities have vast defence networks of traps throughout their many levels. These traps are very creative, including such devices as large round stones to block doors and holes in the ceiling through which the defenders may drop spears.

Throughout the Dark Ages to the Middle Byzantine period, Armenians immigrated in significant numbers into Cappadocia, partly due to imperial policies.^[27] The Arab historian Abu Al Faraj asserts the following about Armenian settlers in Sebasteia, during the 10th century:

They [the Armenians] were assigned the Sebaste (now Siwas) district of Cappadocia. Their number grew to such an extent that they became valuable auxiliaries to the imperial armies. They were employed to garrison the fortresses reconquered from the Arabs (probably Membedj, Dolouk, etc.). They formed excellent infantry for the armies of Basileus in all wars, constantly fighting with courage and success alongside the Romans.^[35]

As a result of the Byzantine military campaigns and the Seljuk invasion of Armenia, the Armenians spread into Cappadocia and eastward from Cilicia into the mountainous areas of northern Syria and Mesopotamia, and the Armenian Kingdom of Cilicia was eventually formed. This immigration was increased further after the decline of the local imperial power and the establishment of the Crusader States following the Fourth Crusade. To the crusaders, Cappadocia was terra Hermeniorum, the land of the Armenians, due to the large number of Armenians settled there.^[36]

In the 9th–11th centuries, the region comprised the themes of Charsianon with its capital at the eponymous city and Cappadocia, which had first its capital in Nyssa and then at Koron, after Nyssa had been sacked by the Arabs in 838.^[37] By the mid-tenth century, the region was again reorganised as much of the no-men's land was resettled, especially around the area of Larissa, Tzamandos, and Lykandos.^[37] After the Byzantine reconquests in the East finished, Cappadocia was again removed from the frontier and an increasingly demilitarised region in the eleventh century.^[38]

Following the Battle of Manzikert in 1071, Turkish clans under the leadership of the Seljuks began settling in Anatolia. With the rise of Turkish power in Anatolia, Cappadocia slowly became a tributary to the Turkish states that were established to the east and to the west; some of the native population converted to Islam^[39] with the rest forming the remaining Cappadocian Greek population.

By the end of the early 12th century, Anatolian Seljuks had established their sole dominance over the region. With the decline and the fall of the Konya-based Seljuks in the second half of the 13th century, they were gradually replaced by successive Turkic ruled states: the Karaman-based Beylik of Karaman and then the Ottoman Empire. Cappadocia remained part of the Ottoman Empire until 1922, when it became part of the modern state of Turkey.^{[citation needed]}

In the early 18th century, a fundamental change occurred in between when a new urban center, Nevşehir, was founded by a grand vizier who was a native of the locality (Nevşehirli Damat İbrahim Pasha), to serve as regional capital, a role the city continues to assume to this day. In the meantime many former Cappadocians had shifted to a Turkish dialect (written in Greek alphabet, Karamanlıca).

Where the Greek language was maintained (Sille, villages near Kayseri, Pharasa town and other nearby villages), it became heavily influenced by the surrounding Turkish. This dialect of Eastern Roman Greek is known as Cappadocian Greek. Following the foundation of Turkey in 1922, those who still identified with this pre-Islamic culture of Cappadocia were required to leave, so this language is now only spoken by a handful of their descendants, most now located in modern Greece.^{[citation needed]}

Cappadocia Church (Turkish: Kapadokya Kilisesi) is a Christian church and local congregation in Avanos, a town in Nevşehir Province in Cappadocia.^{[40][41][42][43][44]} The church holds Turkish-language worship services within a Protestant theological framework, according to its own statements.^[45] Several online travel and business directories list it as one of the places of worship and visitation in Avanos.^[42][43][44]

The area is a popular tourist destination, as it has many areas with unique geological, historic, cultural, and religious features. Touristic Cappadocia includes four cities: Nevşehir, Kayseri, Aksaray and Niğde.^{[citation needed]}

The region is located southwest of the major city Kayseri, which has airline and railway service to Ankara and Istanbul and other cities.^{[citation needed]}

The most important towns and destinations in Cappadocia are Ortahisar, Ürgüp, Göreme, Love Valley, Ihlara Valley, Selime, Güzelyurt, Uçhisar, Avanos and Zelve.^{[citation needed]} Cappadocia is served by Nevşehir Kapadokya Airport (NAV), which functions as the region’s primary airport. According to the Republic of Türkiye Directorate General of State Airports Authority (DHMİ), recent infrastructure and capacity expansion projects have increased the airport’s annual passenger capacity to nearly 2 million, a level considered sufficient for the region’s current tourism demand.^[46]

Sedimentary rocks formed in lakes and streams and ignimbrite deposits that erupted from ancient volcanoes approximately nine to three million years ago, during the late Miocene to Pliocene epochs, underlie the Cappadocia region. The rocks of Cappadocia near Göreme eroded into hundreds of spectacular pillars and minaret-like forms. People of the villages at the heart of the Cappadocia region carved out houses, churches and monasteries from the soft rocks of volcanic deposits.^[47]

Göreme became a Christian monastic centre in 300–1200 AD. The Yusuf Koç, Ortahane, Durmus Kadir and Bezirhane churches in Göreme, and houses and churches carved into rocks in the Uzundere, Bağıldere and Zemi Valleys, all evidence Cappadocia as a centre of early Christian learning and are thus a place of pilgrimage. The Göreme Open Air Museum is the most visited site of the Christian monastic communities in Cappadocia (see Churches of Göreme and Churches of the Ihlara Valley) and is one of the most famous sites in central Turkey. The complex contains more than 30 carved-from-rock churches and chapels, some having superb frescoes inside, dating from the ninth century to the eleventh century.^[48]

The three main castles in Cappadocia are Uçhisar Castle, Ortahisar Castle, and Ürgüp Kadıkalesi (Temenni Tepe). Among the most visited underground cities are Derinkuyu, Kaymakli, Gaziemir and Ozkonak. The best historic mansions and cave houses for tourist stays are in Ürgüp, Göreme, Güzelyurt and Uçhisar.^{[citation needed]}

Hot-air ballooning is especially popular in Cappadocia, particularly around Göreme, offering sunrise flights over the region's fairy chimneys and valleys.^[49]

Trekking is practised in Ihlara Valley, Monastery Valley (Güzelyurt), Ürgüp and Göreme.^{[citation needed]}

In 1975, a study of three small villages in central Cappadocia—Tuzköy, Karain and Sarıhıdır—found that mesothelioma was causing 50% of all deaths. Initially, this was attributed to erionite, a zeolite mineral with similar properties to asbestos, but detailed epidemiological investigation demonstrated that the substance causes the disease mostly in families with a genetic predisposition to mineral fiber carcinogenesis. The studies are being extended to other parts of the region.^[50][51]

The area was featured in several films due to its topography. The 1983 Italian/French/Turkish film Yor, the Hunter from the Future and 1985's Land of Doom were filmed in Cappadocia. The region was used for the 1989 science fiction film Slipstream to depict a cult of wind worshippers. In 2010 and early 2011, the film Ghost Rider: Spirit of Vengeance was filmed in the Cappadocia region.^[52]

Autechre's second album, Amber, features a photo of this region's fairy mountains as the cover art,^[53] being their only album whose cover isn't computer-generated.^{[citation needed]}

Cappadocia's winter landscapes and broad panoramas are prominent in the 2014 film Winter Sleep (Turkish: Kış Uykusu), directed by Nuri Bilge Ceylan, which won the Palme d'Or at the 2014 Cannes Film Festival.^[54]

The 2011 video game Assassin's Creed Revelations features the city as a major location, where the protagonist Ezio Auditore travels to in a bid to stop the Byzantine Templars and their operations, kill Manuel Palaiologos and recover the final Masyaf key.

Since 2012, a multiday track running ultramarathon of desert concept, called Runfire Cappadocia Ultramarathon, is held annually in July. The race tours 244 km (152 mi) in six days through several places across Cappadocia reaching out to Lake Tuz.^[55] In September 2016, for the first time, the Turkish Presidential Bike Tour took place in Cappadocia, with more than 300 cyclists from around the globe participating.^[56]

A hot air balloon is a lighter-than-air aircraft consisting of a bag, called an envelope, which contains heated air. Suspended beneath is a gondola or wicker basket (in some long-distance or high-altitude balloons, a capsule), which carries passengers and a source of heat, in most cases an open flame caused by burning liquid propane. The heated air inside the envelope makes it buoyant, since it has a lower density than the colder air outside the envelope. As with all aircraft, hot air balloons cannot fly beyond the atmosphere. The envelope does not have to be sealed at the bottom, since the air inside the envelope is at about the same pressure as the surrounding air. In modern sport balloons the envelope is generally made from nylon fabric, and the inlet of the balloon (closest to the burner flame) is made from a fire-resistant material such as Nomex. Modern balloons have been made in many shapes, such as rocket ships and the shapes of various commercial products, though the traditional shape is used for most non-commercial and many commercial applications.

The hot air balloon is the first successful human-carrying flight technology. The first untethered manned hot air balloon flight in the world was performed in Paris, France, by Jean-François Pilâtre de Rozier and François Laurent d'Arlandes on November 21, 1783,^[1] in a balloon created by the Montgolfier brothers.^[2] Hot air balloons that can be propelled through the air rather than simply drifting with the wind are known as thermal airships.

A precursor of the hot air balloon was the sky lantern (simplified Chinese: 孔明灯; traditional Chinese: 孔明燈). Zhuge Liang of the Shu Han kingdom, during the Three Kingdoms era (220–280 CE), used these airborne lanterns for military signaling.^[3] The Mongolian army studied Kongming lanterns from China and used them in the Battle of Legnica during the Mongol invasion of Poland in the 13th century.^[4] This is the first time ballooning was known in the western world.

In the 18th century the Portuguese Jesuit priest Bartolomeu de Gusmão in colonial Brazil envisioned an aerial apparatus named Passarola, which was the predecessor of the hot air balloon. The Passarola was intended to serve as an air vessel in order to facilitate communication and as a strategical device.^[5] In 1709 John V of Portugal decided to fund Bartolomeu de Gusmão's project following a petition made by the Jesuit priest,^[6] and an unmanned demonstration was performed at Casa da Índia in the presence of John V and the queen, Maria Anna of Austria, with the Italian cardinal Michelangelo Conti, two members of the Portuguese Royal Academy of History, one Portuguese diplomat and one chronicler serving as witnesses. This event would bring some European attention to this event and this project. A later article dated on October 20, 1786, by the London Daily Universal Register would state that the inventor was able to raise himself by the use of his prototype. Also in 1709, the Portuguese Jesuit wrote Manifesto summário para os que ignoram poderse navegar pelo elemento do ar (Short Manifesto for those who are unaware that is possible to sail through the element air); he also left designs for a manned air vessel.

In the 1970s, balloonist Julian Nott hypothesized that the Nazca Lines geoglyphs' creation two millennia ago could have been guided by Nazca leaders in a balloon, possibly the earliest hot air balloon flights in human history.^[7] To support this theory, in 1975 he designed and piloted the Nazca Prehistoric Balloon, claiming to have used only methods and materials available to the Pre-Inca Peruvians 1,000 years ago.^[8][9]

The French brothers Joseph-Michel and Jacques-Étienne Montgolfier developed a hot-air balloon in Annonay, Ardèche, France, and demonstrated it publicly on September 19, 1783, making an unmanned flight lasting 10 minutes. After experimenting with unmanned balloons and flights with animals, the first balloon flight with humans aboard, a tethered flight, performed on or around October 15, 1783, by Jean-Francois Pilatre de Rozier, who made at least one tethered flight from the yard of the Reveillon workshop in the Faubourg Saint-Antoine. Later that same day, Pilatre de Rozier became the second human to ascend into the air, reaching an altitude of 26 m (85 ft), the length of the tether.^[10][11] The first free flight with human passengers was made a few weeks later, on November 21, 1783.^[2] King Louis XVI had originally decreed that condemned criminals would be the first pilots, but de Rozier, along with Marquis François d'Arlandes, petitioned successfully for the honor.^[12][13][14] The first military use of a hot air balloon happened in 1794 during the battle of Fleurus, when the French used the balloon l'Entreprenant for observation.^[15]

Modern hot air balloons, with an onboard heat source, were developed by Ed Yost and Jim Winker, beginning during the 1950s; their work resulted in his a first successful flight on October 22, 1960.^[16] The first modern hot air balloon to be made in the United Kingdom (UK) was the Bristol Belle, built in 1967. Presently, hot air balloons are used primarily for recreation.

On November 26, 2005 Vijaypat Singhania set the world altitude record for highest hot air balloon flight, reaching 21,027 m (68,986 ft). He took off from downtown Mumbai, India, and landed 240 km (150 mi) south in Panchale.^[17]

The previous record of 19,811 m (64,997 ft) had been set by Per Lindstrand on June 6, 1988, in Plano, Texas.

On January 15, 1991, Per Lindstrand (born in Sweden, but resident in the UK) and Richard Branson of the UK flew 7,671.91 km (4,767.10 mi) from Japan to Northern Canada in the “Virgin Pacific Flyer”. With a volume of 74,000 cubic meters (2.6 million cubic feet), the balloon envelope was the largest ever built for a hot air craft. Designed to fly in the trans-oceanic jet streams, the Pacific Flyer recorded the fastest ground speed for a manned balloon at 394 km/h (245 mph).

The longest duration record was set by Swiss psychiatrist Bertrand Piccard (Auguste Piccard's grandson) and Briton Brian Jones, flying in the Breitling Orbiter 3. It was the first nonstop trip around the world by balloon. The balloon left Château-d'Oex, Switzerland, on March 1, 1999, and landed at 1:02 a.m. on March 21 in the Egyptian desert 500 km (300 mi) south of Cairo. The two men exceeded distance, endurance, and time records, traveling 19 days, 21 hours, and 55 minutes.

Steve Fossett, flying solo, exceeded the record for briefest time traveling around the world on 3 July 2002 on his sixth attempt,^[18] in 320 h 33 min.^[19] Fedor Konyukhov flew solo round the world on his first attempt in a hybrid hot air/helium balloon from 11 to 23 July 2016^[20] for a round-the world time of 268 h 20 min.^[19]

A hot air balloon for manned flight uses a single-layered, fabric gas bag (lifting "envelope"), with an opening at the bottom called the mouth or throat. Attached to the envelope is a basket, or gondola, for carrying the passengers. Mounted above the basket and centered in the mouth is the "burner", which injects a flame into the envelope, heating the air within. The heater or burner is fueled by propane, a liquefied gas stored in pressure vessels, similar to high-pressure forklift cylinders.^[21][22]

Modern hot air balloons are usually made of materials such as ripstop nylon or dacron (a polyester).^[23]

During the manufacturing process, the material is cut into panels and sewn together, along with structural load tapes that carry the weight of the gondola or basket. The individual sections, which extend from the throat to the crown (top) of the envelope, are known as gores or gore sections. Envelopes can have as few as 4 gores or as many as 24 or more.^[24]

Envelopes often have a crown ring at their very top. This is a hoop of smooth metal, usually aluminium, and approximately 30 cm (1 ft) in diameter. Vertical load tapes from the envelope are attached to the crown ring.

At the bottom of the envelope the vertical load tapes are sewn into loops that are connected to cables (one cable per load tape). These cables, often referred to as flying wires, are connected to the basket by carabiners.

The most common technique for sewing panels together is called the French felled, French fell, or double lap seam.^{[25][26][27][28]} The two pieces of fabric are folded over on each other at their common edge, possibly with a load tape as well, and sewn together with two rows of parallel stitching. Other methods include a flat lap seam, in which the two pieces of fabric are held together simply with two rows of parallel stitching, and a zigzag, where parallel zigzag stitching holds a double lap of fabric.^[27]

The fabric (or at least part of it, the top 1/3, for example) may be coated with a sealer, such as silicone or polyurethane, to make it impermeable to air.^[29] It is often the degradation of this coating and the corresponding loss of impermeability that ends the effective life of an envelope, not weakening of the fabric itself. Heat, moisture, and mechanical wear-and-tear during set-up and pack-up are the primary causes of degradation. Once an envelope becomes too porous to fly, it may be retired and discarded or perhaps used as a "rag bag": cold-inflated and opened for children to run through. Products for recoating the fabric are becoming available commercially.^[30]

A range of envelope sizes is available. The smallest, one-person, basket-less balloons (called "Hoppers" or "Cloudhoppers") have as little as 600 m³ (21,000 cu ft) of envelope volume;^[31] for a perfect sphere the radius would be around 5 m (16 ft). At the other end of the scale, balloons used by commercial sightseeing operations may be able to carry well over two dozen people, with envelope volumes of up to 17,000 m³ (600,000 cu ft).^[31] The most-used size is about 2,800 m³ (99,000 cu ft), allowing to carry 3 to 5 people.

The top of the balloon usually has a vent of some sort, enabling the pilot to release hot air to slow an ascent, start a descent, or increase the rate of descent, usually for landing. Some hot air balloons have turning vents, which are side vents that, when opened, cause the balloon to rotate. Such vents are particularly useful for balloons with rectangular baskets, to facilitate aligning the wider side of the basket for landing.^[32]

The most common type of top vent is a disk-shaped flap of fabric called a parachute vent, invented by Tracy Barnes.^[33] The fabric is connected around its edge to a set of "vent lines" that converge in the center. (The arrangement of fabric and lines roughly resembles a parachute—thus the name.) These "vent lines" are themselves connected to a control line that runs to the basket. A parachute vent is opened by pulling on the control line. Once the control line is released, the pressure of the remaining hot air pushes the vent fabric back into place. A parachute vent can be opened briefly while in flight to initiate a rapid descent. (Slower descents are initiated by allowing the air in the balloon to cool naturally.) The vent is pulled open completely to collapse the balloon after landing.

An older, and presently less commonly used, style of top vent is called a "Velcro-style" vent. This too is a disk of fabric at the top of the balloon. However, rather than having a set of "vent lines" that can repeatedly open and close the vent, the vent is secured by "hook and loop" fasteners (such as Velcro) and is only opened at the end of the flight. Balloons equipped with a Velcro-style vent typically have a second "maneuvering vent" built into the side (as opposed to the top) of the balloon. Another common type of top design is the "smart vent", which, rather than lowering a fabric disc into the envelope as in the "parachute" type, gathers the fabric together in the center of the opening. This system can theoretically be used for in-flight maneuvering, but is more commonly used only as a rapid-deflation device for use after landing, of particular value in high winds. Other designs, such as the "pop top" and "MultiVent" systems, have also attempted to address the need for rapid deflation on landing, but the parachute top remains popular as an all-around maneuvering and deflation system.

Besides special shapes, possibly for marketing purposes, there are several variations on the traditional "inverted tear drop" shape. The simplest, often used by home builders, is a hemisphere on top of a truncated cone. More sophisticated designs attempt to minimize the circumferential stress on the fabric, with different degrees of success depending on whether they take fabric weight and varying air density into account. This shape may be referred to as "natural".^[34] Finally, some specialized balloons are designed to minimize aerodynamic drag (in the vertical direction) to improve flight performance in competitions.^[35]

Hot air balloon baskets are commonly made of woven wicker or rattan. These materials have proven to be sufficiently light, strong, and durable for balloon flight. Such baskets are usually rectangular or triangular in shape. They vary in size from just big enough for two people to large enough to carry thirty.^[36] Larger baskets often have internal partitions for structural bracing and to compartmentalize the passengers. Small holes may be woven into the side of the basket to act as foot holds for passengers climbing in or out.^[37]

Baskets may also be made of aluminium, especially a collapsible aluminium frame with a fabric skin, to reduce weight or increase portability.^[38] These may be used by pilots without a ground crew or who are attempting to set altitude, duration, or distance records. Other specialty baskets include the fully enclosed gondolas used for around-the-world attempts^[39] and baskets that consist of little more than a seat for the pilot and perhaps one passenger.

The burner unit gasifies liquid propane,^[40] mixes it with air, ignites the mixture, and directs the flame and exhaust into the mouth of the envelope. Burners vary in power output; each will generally produce 2 to 3 MW of heat (7 to 10 million BTUs per hour), with double, triple, or quadruple burner configurations installed where more power is needed.^[41][42] The pilot actuates a burner by opening a propane valve, known as a blast valve. The valve may be spring-loaded, so that it closes automatically, or it may stay open until closed by the pilot. The burner has a pilot light to ignite the propane and air mixture. The pilot light may be lit by the pilot with an external device, such as a flint striker or a lighter, or with a built-in piezoelectric spark.^[43]

Where more than one burner is present, the pilot can use one or more at a time, depending on the desired heat output. Each burner has a metal coil of propane tubing the flame shoots through to preheat the incoming liquid propane. The burner unit may be suspended from the mouth of the envelope or supported rigidly over the basket. The burner unit may be mounted on a gimbal to enable the pilot to aim the flame and avoid overheating the envelope fabric. A burner may have a secondary propane valve that releases propane more slowly and thereby generates a different sound. This is called a whisper burner and is used for flight over livestock to lessen the chance of spooking them. It also generates a more yellow flame and is used for night glows because it lights up the inside of the envelope better than the primary valve.

Propane fuel tanks are usually cylindrical pressure vessels made from aluminium, stainless steel, or titanium with a valve at one end to feed the burner and to refuel. They may have a fuel gauge and a pressure gauge. Common tank sizes are 38, 57 and 76 litres (10, 15 and 20 US gallons).^[29] They may be intended for upright or horizontal use and may be mounted inside or outside the basket.

The pressure necessary to force the fuel through the line to the burner may be supplied by the vapor pressure of the propane itself, if warm enough, or by the introduction of an inert gas such as nitrogen.^[43] Tanks may be preheated with electrical heat tapes to produce sufficient vapor pressure for cold-weather flying.^[44] Warmed tanks are usually also wrapped in an insulating blanket to preserve heat during the setup and flight.

A balloon may be outfitted with a variety of instruments to aid the pilot. These commonly include an altimeter, a rate-of-climb (vertical-speed) indicator known as a variometer, envelope (air) temperature, and ambient (air) temperature.^[45] A GPS receiver can be useful to indicate ground speed (traditional aircraft air-speed indicators would be useless) and direction.

Increasing the air temperature inside the envelope makes it less dense than the surrounding (ambient) air. The balloon floats because of the buoyant force exerted on it. This force is the same force that acts on objects when they are in water and is described by Archimedes' principle. The amount of lift (or buoyancy) provided by a hot air balloon depends primarily upon the difference between the temperature of the air inside the envelope and the temperature of the air outside the envelope. For most envelopes made of nylon fabric, the maximal internal temperature is limited to approximately 120 °C (250 °F).^[46]

The melting point of nylon is significantly greater than this maximal operating temperature—about 230 °C (450 °F)—but higher temperatures cause the strength of the nylon fabric to degrade more quickly over time. With a maximal operating temperature of 120 °C (250 °F), balloon envelopes can generally be flown for between 400 and 500 hours before the fabric needs to be replaced. Many balloon pilots operate their envelopes at temperatures significantly less than the maximum to extend envelope-fabric life.

The lift generated by 2,800 m³ (100,000 cu ft) of dry air heated to various temperatures may be calculated as follows:

Air temperature °C (°F)	Air density kg/m3 (lb/cu ft)	Air mass kg (lb)	Lift generated kg (lb)
20 (68)	1.2041 (0.07517)	3,409.7 (7,517)	0, (0)
99 (210)	0.9486 (0.05922)	2,686.2 (5,922)	723.5 (1,595)
120 (248)	0.8978 (0.05605)	2,542.4 (5,605)	867.3 (1,912)

The density of air at 20 °C (68 °F) is about 1.2 kg/m³ (0.075 lb/cu ft). The total lift for a balloon of 2,800 m³ (100,000 cu ft) heated to 99 °C (210 °F) would be 723.5 kg (1,595 lb). This is just enough to generate neutral buoyancy for the total system mass (not including the heated air trapped in the envelope, of course) stated in the previous section. Liftoff would require a slightly greater temperature, depending on the desired rate of climb. In reality, the air contained in the envelope is not all at the same temperature, as the accompanying thermal image shows, and so these calculations are based on averages.

For typical atmospheric conditions (20 °C or 68 °F), a hot air balloon heated to 99 °C (210 °F) requires about 3.91 m³ of envelope volume to lift 1 kilogram (equivalently, 62.5 cu ft/lb). The precise amount of lift provided depends not only upon the internal temperature mentioned above, but the external temperature, altitude above sea level, and humidity of the air surrounding. On a warm day, a balloon cannot lift as much as on a cool day, because the temperature required for launch will exceed the maximum sustainable for nylon envelope fabric. Also, in the lower atmosphere, the lift provided by a hot air balloon decreases about 3% per 1,000 m (1% per 1,000 ft) of altitude gained.^[47]

There are several different types of hot air balloons, all with different means of taking and sustaining flight.

Standard hot air balloons are known as Montgolfier balloons and rely solely on the buoyancy of hot air provided by the burner and contained by the envelope.^[48] This style of balloon was developed by the Montgolfier brothers and had its first public demonstration on 4 June 1783 with an unmanned flight lasting 10 minutes, followed later that year with manned flights.^[49]

Instead of using regular air it is also possible to use lighter than air gasses such as Helium or Hydrogen to lift the balloon,^[51] though this means it is technically not a hot air balloon, though they did influence the design of hybrid balloons.

The 1785 Rozière balloon, is the main type of hybrid balloon, named after its creator, Jean-François Pilâtre de Rozier. It has a separate cell for a lighter-than-air gas (typically helium), as well as a cone below for hot air (as is used in a hot air balloon) to heat the helium at night. Hydrogen gas was used in the very early stages of development but was quickly abandoned due to the danger of introducing an open flame near the gas, for example when Rozier attempted to cross the English Channel with his prototype, the fire used to heat the air ignited the Hydrogen and killed both him and his copilot thirty minutes after takeoff.^[52] As such, all modern hybrid balloons now use helium as a lifting gas.^[53] These balloons are commonly used for high performance records for hot air balloons.

Solar balloons are hot air balloons that use just solar energy captured by an envelope. These envelopes are more specialized than for other hot air balloons, trying to maximize the amount of solar energy they collect. This can be accomplished by rotating the envelope during flight or by having the envelope colored black or another dark color.^[54] They were pioneered in the 1970s in Europe by Tracy Barnes, Dominic Michaelis, and in the US by Frederick Espoo and Paul Woessher.^[55]

A Thermal airship, or blimp, became a reality in the 1960s. Thermal airships were the first steerable air buoyant vehicles.^[56] They utilized tail fins and a rudder and contained strictly hot air rather than a mix with hydrogen or helium.^[56]

Observation balloons were deployed as early as the American Civil War and used as reconnaissance towers.^[57] The first military funded balloon in America was designed by Thaddeus Lowe on August 2, 1861, for the Union.^[57] His design utilized gas from municipal lines to inflate the balloon as he did not have access to a portable generator.^[57] Observation balloons during this time were all made using multicolored-silk, wicker baskets, and were vertically oriented and tear shaped.^[58] Hydrogen, or illumination gas became the most used inflation fuel by the 20th Century, as it was lighter than air.^[58] Observation balloon usage skyrocketed in Britain by the Royal Engineers at the end of the 19th Century, deploying to Sudan in 1885 and to South Africa during the Second Boer War from 1899 to 1902.^[59]

Due to the overall design of hot air balloons, controlled and precise steering of hot air balloons is not possible; it is possible for pilots to try to achieve basic directional control by changing altitude and catching different wind streams.^[60] Wind in the northern hemisphere tends to turn east due to coriolis effect as the altitude increases.

The most effective way of landing a hot air balloon is to reduce the energy in the envelope, either by turning down the flame in Montgolfier and Hybrid balloons, or more directly by opening a flap in the envelope that will release the air/gas inside.^[60]

To help ensure the safety of pilot and passengers, a hot air balloon may carry several pieces of safety equipment.

To relight the burner if the pilot light goes out and the optional piezo ignition fails, the pilot should have ready access to a means of backup ignition, such as a flint spark lighter. Many systems, especially those that carry passengers, have completely duplicate fuel and burner systems: two fuel tanks, connected to two separate hoses, which feed two distinct burners. This enables a safe landing in the case of a blockage somewhere in one system or if a system must be disabled because of a fuel leak.

A fire extinguisher suitable for extinguishing propane fires is useful. Most balloons carry a 1 or 2 kg AB:E type fire extinguisher.^[61]

A handling or drop line is mandatory safety equipment in many countries. This is a rope or webbing of 20–30 meters in length attached to the balloon basket with a quick-release connection at one end. In very calm winds the balloon pilot can throw the handling line from the balloon so that the ground crew can guide the balloon safely away from obstructions on the ground.^[62]

For commercial passenger balloons, a pilot restraint harness is mandatory in some countries. This consists of a hip belt and a webbing line that together allow for some movement while preventing the pilot from being ejected from the basket during a hard landing.

Further safety equipment may include a first-aid kit, a fire blanket and a strong rescue knife.

At a minimum, the pilot should wear leather or flame-retardant fiber (such as nomex) gloves, so that they may shut off a gas valve in the case of a leak, even if there is a flame present; quick action in this regard can turn a potential catastrophe into a mere inconvenience. The pilot should additionally wear flame-resistant clothing covering their arms and legs; either natural fiber, such as cotton, linen, hemp, or wool, or engineered flame-retardant fiber, such as nomex, is acceptable in this capacity. Most engineered fibers (with the exception of rayon, which is also safe to wear) are thermoplastic; many are also hydrocarbons. This makes such fabrics very much unsuitable to wear near high temperatures, since non-flame-retardant thermoplastics will melt onto the wearer, and most hydrocarbons, whether fibrous or not, are suitable to use as fuels. Natural fiber will singe rather than melt or burn readily, and flame-retardant fiber generally has a very high melting point and is intrinsically non-flammable. Many pilots also advise their passengers to wear similar protective clothing that covers their arms and legs, as well as strong shoes or boots that offer good ankle support. Finally, some balloon systems, especially those that hang the burner from the envelope instead of supporting it rigidly from the basket, require the use of helmets by the pilot and passengers.

The ground crew should wear gloves whenever there is a possibility of handling ropes or lines. The mass and exposed surface to air movement of a medium-sized balloon is sufficient to cause rope friction burns to the hands of anyone trying to stop or prevent movement. The ground crew should also wear sturdy shoes and at least long pants in case of the need to access a landing or landed balloon in rough or overgrown terrain.

As with aircraft, hot air balloons require regular maintenance to remain airworthy. As aircraft made of fabric and that lack direct horizontal control, hot air balloons may occasionally require repairs to rips or snags. While some operations, such as cleaning and drying, may be performed by the owner or pilot, other operations, such as sewing, must be performed by a qualified repair technician and recorded in the balloon's maintenance log book.

To ensure long life and safe operation, the envelope should be kept clean and dry. This prevents mold and mildew from forming on the fabric and abrasion from occurring during packing, transport, and unpacking due to contact with foreign particles. In the event of a landing in a wet (because of precipitation or early morning or late evening dew) or muddy location (farmer's field), the envelope should be cleaned and laid out or hung to dry.

The burner and fuel system must also be kept clean to ensure safe operation on demand. Damaged fuel hoses need to be replaced. Stuck or leaky valves must be repaired or replaced. The wicker basket may require occasional refinishing or repair. The skids on its bottom may require occasional replacement.

Balloons in most parts of the world are maintained in accordance with a fixed manufacturer's maintenance schedule that includes regular (100 flight hours or 12 month) inspections, in addition to maintenance work to correct any damage. In Australia, balloons used for carrying commercial passengers must be inspected and maintained by approved workshops.^[63]

In the case of a snag, burn, or rip in the envelope fabric, a patch may be applied or the affected panel completely replaced. Patches may be held in place with glue, tape, stitching, or a combination of these techniques. Replacing an entire panel requires the stitching around the old panel to be removed, and a new panel to be sewn in with the appropriate technique, thread, and stitch pattern.

Depending on the size of the balloon, location, and intended use, hot air balloons and their pilots need to comply with a variety of regulations.

As with other aircraft in the US, balloons must be registered (have an N-number), have an airworthiness certificate, and pass annual inspections. Balloons below a certain size (empty weight of less than 155 pounds or 70 kg including envelope, basket, burners and empty fuel tanks) can be used as an ultralight aircraft.

In Australia, private balloon pilots are managed by the Australian Ballooning Federation^[64] and typically become members of regional hot air ballooning clubs. Commercial operations carrying fare paying passengers or charging for promotional flights must operate under an Air Operators Certificate from the Australian Civil Aviation and Safety Authority (CASA) with a nominated Chief Pilot. Pilots must have different degrees of experience before they are allowed to progress to larger balloons. Hot air balloons must be registered aircraft with CASA and are subject to regular airworthiness checks by authorised personnel.^[65]

In the UK, the person in command must hold a valid Private Pilot's Licence issued by the Civil Aviation Authority specifically for ballooning; this is known as the PPL(B). There are two types of commercial balloon licences: CPL(B) Restricted and CPL(B) (Full). The CPL(B) Restricted is required if the pilot is undertaking work for a sponsor or being paid by an external agent to operate a balloon. The pilot can fly a sponsored balloon with everything paid for with a PPL unless asked to attend any event. Then a CPL(B) Restricted is required. The CPL(B) is required if the pilot is flying passengers for money. The balloon then needs a transport category C of A (certificate of air worthiness). If the pilot is only flying sponsor's guests and not charging money for flying other passengers, then the pilot is exempted from holding an AOC (air operator's certificate) though a copy of it is required.^{[clarification needed]} For passenger flying the balloon also requires a maintenance log.

In the United States, a pilot of a hot air balloon must have a pilot certificate from the Federal Aviation Administration (FAA), carrying the rating of "Lighter-than-air free balloon", and unless the pilot is also qualified to fly gas balloons, will also carry this limitation: "Limited to hot-air balloons with airborne heater". A pilot does not need a license to fly an ultralight aircraft, but training is highly advised, and some hot-air balloons meet the criteria.

To carry paying passengers for hire (and attend some balloon festivals), a pilot must have a commercial pilot certificate. Commercial hot air balloon pilots may also act as hot air balloon flight instructors. While most balloon pilots fly for the pure joy of floating through the air, many are able to make a living as a professional balloon pilot. Some professional pilots fly commercial passenger sightseeing flights, while others fly corporate advertising balloons.^[66]

The largest manufacturer of hot air balloons is Cameron Balloons of Bristol, England, which also owns Lindstrand Balloons of Oswestry, England. Cameron Balloons, Lindstrand Balloons and another English balloon manufacturing company Thunder and Colt (since acquired by Cameron) have been innovators and developers of special shaped balloons. These hot-air balloons use the same principle of lift as conventional inverted teardrop-shaped balloons, but often sections of the special balloon envelope shape do not contribute to the balloon's ability to stay aloft.

The second largest manufacturer of hot air balloons is Ultramagic company, based in Spain, which produces from 80 to 120 balloons per year. Ultramagic can produce very large balloons, such as the N-500 that accommodates as many as 27 persons in the basket, and has also produced many balloons with special shapes, as well as cold-air inflatables.

One of the three largest companies in the world is Kubicek Balloons. From its factory in Brno, Czechia the company ships its products worldwide. Produces from 100 to 115 balloons per year. Kubicek company also focus on special shape balloons, FAA/EASA type certified and are delivered with a Standard Airworthiness Certificate.

In the USA Aerostar International, Inc. of Sioux Falls, South Dakota was North America's largest balloon manufacturer and a close second in world manufacturing before ceasing to build balloons in January 2007. The oldest U.S. certified manufacturer is now Adams Balloons out of Albuquerque, New Mexico. Firefly Balloons, formerly The Balloon Works, is a manufacturer of hot air balloons in Statesville, North Carolina. Another manufacturer is Head Balloons, Inc. of Helen, Georgia.

The major manufacturers in Canada are Sundance Balloons and Fantasy Sky Promotions. Other manufacturers include Kavanagh Balloons of Australia, Schroeder Fire Balloons of Germany, Kubicek Balloons of the Czech Republic, and LLopis Balloons of France.
