Auvergne_(region)

Auvergne (; French: [ovɛʁɲ] ; Occitan: Auvèrnhe or Auvèrnha) is a cultural region in central France.
Since 2016, Auvergne is not an administrative unit of France, but it is generally regarded as similar to the land area of the Province of Auvergne, which was dissolved in 1790, and the larger administrative region of Auvergne, which existed from 1956 to 2015.
The region is home to a chain of volcanoes known collectively as the "chaîne des Puys". The last confirmed eruption was around 4040 BCE. The volcanoes began forming about 70,000 years ago, and most have eroded, leaving plugs of hardened magma that form rounded hilltops known as puys.
