Clermont-Ferrand sits on the plain of Limagne in the Massif Central and is surrounded by a major industrial area. The city is known for the chain of volcanoes, the Chaîne des Puys, which surround it. This includes the dormant volcano Puy de Dôme, 10 kilometres (6 miles) away, one of the highest in the surrounding area, which is topped by communications towers and visible from the city. Clermont-Ferrand has been listed as a "tectonic hotspot" since July 2018 on the UNESCO World Heritage List.
One of the oldest French cities, it was known by the Romans in the first century as the capital of the Arvernie tribe before developing in the Gallo-Roman era under the name of Augustonemetum in the 1st century BC. The forum of the Roman city was located on the top of the Clermont mound, on the site of the present cathedral. During the decline of the Western Roman Empire it was subjected to repeated looting by the peoples who invaded Gaul, including Vandals, Alans, Visigoths and Franks. It was later raided by Vikings in the ninth and tenth century AD as the Carolingian Empire weakened in the early Middle Ages. Growing in importance under the Capetian dynasty, in 1095 it hosted the Council of Clermont, where Pope Urban II called the First Crusade. In 1551, Clermont became a royal town, and was declared an inseparable property of the Crown in 1610.
Today Clermont-Ferrand hosts the Clermont-Ferrand International Short Film Festival (), one of the world's leading festivals for short films. It is also home to the corporate headquarters of Michelin, the global tyre company founded in the city more than 100 years ago. With a quarter of the municipal population being students, and some 6,000 researchers, Clermont-Ferrand is the first city in France to join the UNESCO Learning City Network .
Among the many notable landmarks in Clermont-Ferrand are the black lava-stone Gothic Cathedral and the Place de Jaude with an equestrian statue of Vercingetorix made by Frédéric Bartholdi, surmounting the words inscribed in French "J'ai pris les armes pour la liberte de tous" ("I took up arms for the liberty of all").
History
Name
Clermont-Ferrand's first name was Augustonemetum, Latin for "sanctuary for Augustus", or (town of the Arverni people). It originated on the central knoll where the cathedral is situated today, overlooking the capital of . The fortified castle of Clarus Mons gave its name to the whole town in 848, to which the small episcopal town of Montferrand was attached in 1731, together taking the name of Clermont-Ferrand. The amalgamation of the two towns was decreed by Louis XIII and confirmed by Louis XV. The old part of Clermont is delimited by the route of the ramparts as they existed at the end of the Middle Ages.
Prehistory and Roman era
Clermont ranks among the oldest cities of France. The first known mention was by the Greek geographer Strabo, who called it the "metropolis of the Arverni" (meaning their oppidum civitas or tribal capital). The city was at that time called Nemessos, a Gaulish word for a sacred forest, and was situated on the mound where the cathedral of Clermont-Ferrand stands today. Somewhere in the area around Nemossos, the Arverni chieftain Vercingetorix (later to head a unified Gallic resistance to the Roman invasion led by Julius Caesar) was born around 72 BC. Nemossos was situated not far from the plateau of Gergovia, where Vercingetorix repulsed the Roman assault at the Battle of Gergovia in 52 BC. After the Roman conquest, the city became known as Augustonemetum. The city also boasts an expansive and largely uncharted network of manmade underground cavities, or souterrains, some of which were in use during Gallo-Roman times.
Early Middle Ages The city became the seat of a bishop in the 5th century, at the time of the bishop Namatius, who built a cathedral here described by Gregory of Tours. Clermont went through a dark period after the disappearance of the Roman Empire and during the High Middle Ages was pillaged by the peoples who invaded Gaul. Between 471 and 475, Auvergne was often the target of Visigothic expansion, and the city was frequently besieged, including once by Euric. Although defended by Sidonius Apollinaris, at the head of the diocese from 468 to 486, and the patrician Ecdicius, the city was ceded to the Visigoths by emperor Julius Nepos in 475 and remained part of the Visigothic kingdom until 507. A generation later, it became part of the Kingdom of the Franks. On 8 November 535, the first Council of Clermont opened at Arvernis (Clermont), with fifteen bishops participating, including Caesarius of Arles, Nizier of Lyons, the Bishop of Trier, and Saint Hilarius, Bishop of Mende. The Council issued 16 decrees. The second canon reiterated the principle that the granting of episcopal dignity must be made according to merit and not as a result of intrigues.
In 570, Bishop Avitus ordered the Jews of the city, who numbered over 500, to accept Christian baptism or be expelled. as quoted by
In 848, the city was renamed Clairmont, after the castle Clarus Mons. During this era, it was an episcopal city ruled by its bishop. Clermont was not spared by the Vikings at the time of the weakening of the Carolingian Empire: it was ravaged by the Normans under Hastein in 862 and 864 and, while its bishop Sigon carried out reconstruction work, again in 898 (or 910, according to some sources). Bishop Étienne II built a new Romanesque cathedral which was consecrated in 946. It was almost entirely replaced by the current Gothic cathedral, though the crypt survives and the towers were only replaced in the 19th century.
Middle Ages
Clermont was the starting point of the First Crusade, in which Christendom sought to retake Muslim-ruled Jerusalem. Pope Urban II called for the crusade in 1095 at the Second Council of Clermont. In 1120, following repeated crises between the counts of Auvergne and the bishops of Clermont and in order to counteract the clergy's power, the counts founded the rival city of Montferrand on a mound next to the fortifications of Clermont, on the model of the new cities of the Midi that appeared in the 12th and 13th centuries. Until the early modern period, the two remained separate cities: Clermont, an episcopal city; Montferrand, a comital one.
Early modern and modern eras
Clermont became a royal city in 1551, and in 1610, the inseparable property of the French Crown. On 15 April 1630 the Edict of Troyes (the First Edict of Union) joined the two cities of Clermont and Montferrand. This union was confirmed in 1731 by Louis XV with the Second Edict of Union. At this time, Montferrand was no more than a satellite city of Clermont, and it remained so until the beginning of the 20th century. Wishing to retain its independence, Montferrand made three demands for independence, in 1789, 1848, and 1863. The Hôtel de Ville (City Hall) was completed in 1844.
In the 20th century, the construction of the Michelin factories and of city gardens, which shaped modern Clermont-Ferrand, united the two cities, although two distinct downtowns survive and Montferrand retains a strong identity.
Geography
Climate Clermont-Ferrand has an oceanic climate (Cfb). The city is in the rain shadow of the Chaîne des Puys, giving it one of the driest climates in metropolitan France, except for a few places around the Mediterranean Sea. The mountains also block most of the oceanic influence of the Atlantic, which creates a much more continental climate than in nearby cities west or north of the mountains, like Limoges and Montluçon. Thus the city has comparatively cold winters and hot summers. From November to March, frost is very frequent, and the city, being at the bottom of a valley, is frequently subject to temperature inversion, in which the mountains are sunny and warm, and the plain is freezing cold and cloudy. Snow is quite common, although usually short-lived and light. Summer temperatures sometimes exceed , with violent thunderstorms. The highest temperature was reached in 2019 of while the lowest was .
Main sights
Religious architecture
Clermont-Ferrand has two famous churches. One is Notre-Dame du Port, a Romanesque church which was built during the 11th and 12th centuries (the bell tower was rebuilt during the 19th century). It was nominated as a World Heritage Site by UNESCO in 1998. The other is Clermont-Ferrand Cathedral (Cathédrale Notre-Dame-de-l'Assomption de Clermont-Ferrand), built in Gothic style between the 13th and the 19th centuries.

Economy and infrastructure Food production and processing as well as engineering are major employers in the area, as are the many research facilities of leading computer software and pharmaceutical companies.
The city's industry was for a long time linked to the French tyre manufacturer Michelin, which created the radial tyre and expanded from Clermont-Ferrand to become a worldwide leader in its industry. For most of the 20th century, it had extensive factories throughout the city, employing up to 30,000 workers. While the company has maintained its headquarters in the city, most of the manufacturing is now done in foreign countries. This downsizing took place gradually, allowing the city to court new investment in other industries, thus avoiding the fate of many post-industrial cities and keeping it a very wealthy and prosperous area home to many high-income executives.
Transport
The main railway station has connections to Paris and several regional destinations: Lyon, Moulins via Vichy, Le Puy-en-Velay, Aurillac, Nîmes, Issoire, Montluçon and Thiers.
The A71 motorway connects Clermont-Ferrand with Orléans and Bourges, the A75 with Montpellier and the A89 with Bordeaux, Lyon and Saint-Étienne (A72). The airport offers flights within France. Recently, Clermont-Ferrand was France's first city to get a new Translohr transit system, the Clermont-Ferrand tramway, thereby linking the city's north and south neighbourhoods.
The TGV will arrive in Auvergne after 2030. It will be one of the last regions not to have a TGV stop.
Clermont-Ferrand Auvergne Airport serves only a handful of mostly domestic destinations. For international travel, the city is served by the nearest international airport, Lyon–Saint-Exupéry Airport, which is located to the east of Clermont-Ferrand.
Population
Culture
Clermont-Ferrand was the home of mathematician and philosopher Blaise Pascal, who tested Evangelista Torricelli's hypothesis concerning the influence of gas pressure on liquid equilibrium. This is the experiment in which a vacuum is created in a mercury tube; Pascal's experiment had his brother-in-law carry a barometer to the top of the Puy-de-Dôme. The Université Blaise-Pascal (or Clermont-Ferrand II) was located primarily in the city and is named after him.
