the department named after this volcano

Volcanic mountain in France

Puy de Dôme (/US/,/p//w//iː// //d//ə// /'/d//oʊ//m/, pɥi də dom) is a lava dome and one of the youngest volcanoes in the Chaîne des Puys region of Massif Central in central France. This chain of volcanoes including numerous cinder cones, lava domes and maars is far from the edge of any tectonic plate. Puy de Dôme was created by a Peléan eruption, some 10,700 years ago. Puy de Dôme is approximately from Clermont Ferrand. The Puy de Dôme [[Departments of France is named after the volcano.

In pre Christian Europe, Puy de Dôme served as an assembly place for spiritual ceremonies. Temples were built at the summit, including a Gallo Roman temple of Mercury, the ruins of which were discovered in 1872. In 1648, Florin Périer, at the urging of Blaise Pascal, supported Evangelista Torricelli's theory that barometric observations were caused by the weight of air by measuring the height of a column of mercury at three elevations on Puy de Dôme. In 1875, a physics laboratory was built at the summit. Since 1956, a TDF (Télédiffusion de France) antenna is also located there. On the top of the mountain, there is a transmitter for FM and TV.

A UNESCO World Heritage site since 2018, the Puy de Dôme is one of the most visited sites in the Auvergne region, attracting nearly 500,000 visitors a year. The summit offers expansive views of the Chaîne des Puys and Clermont Ferrand. It is a well known centre for paragliding. The summit can be reached by two pedestrian paths: a southern one ("Le sentier des muletiers", formerly a Roman road) and a northern one ("Le sentier des chèvres") which runs past the Nid de la Poule crater. The GR 4 long distance trail includes both paths to cross the mountain. Since May 2012, visitors can also go up the mountain by train with the Panoramique des Dômes, a rack railway. A road exists along the railway but it is closed to general traffic, except for the military, service vehicles or emergencies. At the top of the mountain, restaurants and shops are available as well as a visitor centre giving information on the history and geology of the area.

In respect of its key role in the development of volcanology as a geoscience discipline, the Puy de Dôme and Petite Puy de Dôme volcanoes were included by the International Union of Geological Sciences (IUGS) in its assemblage of 100 'geological heritage sites' around the world in a listing published in October 2022.

In more recent times, Puy de Dôme has served as an occasional stage finish in the Tour de France. It was here that in 1964 Raymond Poulidor battled with Jacques Anquetil in one of the race's most famous moments, racing side by side up almost the entire climb; and that in 1975 Eddy Merckx was punched in the kidney by a spectator. Between the 1988 and 2023 Tour de France summit finishes, only the first part of the ascent to the Col de Ceyssat was covered in the 13th stage of the 2020 Tour de France. The 2012 construction of a rack railway narrowed the already very narrow road to the top. Because of the increasing logistical demands of the Tour, many thought that the Tour would never return to the Puy de Dôme after 1988. But the 9th stage of the 2023 Tour de France had a summit finish, which was won by Michael Woods. The road is open to cyclists only during very limited periods (when other vehicles are prohibited). In 2006 this was 7–9am on Wednesdays and Sundays between 1 May and 30 September.

The Circuit de Charade was a motorsport street circuit built in 1957 using pre existing roads around the base of the Puy de Dôme. The venue hosted the French Grand Prix as well as the French motorcycle Grand Prix several times in the 1960s and early 1970s.

While the lower areas of the mountain are firmly oceanic (Köppen: Cfb), Puy de Dôme has a humid continental (Köppen: Dfb) with borderline subalpine characteristics, thanks to its high elevation. Its classification is determined from its January average being well below the 3 °C (27 °F) threshold (with 5 °C (23 °F) as its usual lows), and from having over 4 months of average temperatures that exceed 10 °C (50 °F) (the requirement for this climate category is to have at least 3 such months).
