Creux de l'Enfer, Contemporary art museum in Vallée des Usines, Thiers, France.

Creux de l'Enfer is a contemporary art museum in a former factory building in Thiers that has been transformed into exhibition spaces across multiple levels. The venue displays artworks in various media while preserving the industrial structure of its original location.

A sharpening wheel owned by Jehan Ahon Florat stood at the foot of the "rocher de l'enfer" by 1476. The present building, mentioned as housing martinets in 1836, was bought by Pierre Delaire in the 1880s and rebuilt in the first quarter of the 20th century, probably after a fire. Garret forged and cut knife blades there in the 1920s and 1930s; the factory closed in 1956 and reopened as an art centre in 1988, three years after the city's metal sculpture symposium.

The name comes from the workers' saying that even the devil would not live in the factory, and a red devil over two metres tall, painted in 1934 by Louis Guelpa and his brother, still serves as the centre's logo. Exhibitions change each quarter, with past shows by Mona Hatoum, Erró and Tadashi Kawamata.

The museum is open on most afternoons and can be reached on foot from the town center. Plan to spend time on multiple levels as exhibitions are distributed throughout the building, and groups can arrange guided tours.

The name comes from the "rocher de l'enfer", the rock in the Durolle valley where, according to the accounts used by Gregory of Tours, the martyr Saint Genes was beheaded. A knife-sharpening wheel owned by Jehan Ahon Florat stood at its foot by 1476. Workers later said even the devil would not live in the factory, and a red devil over two metres tall, painted in 1934 by Louis Guelpa and his brother, still serves as the art centre's logo.
