An underground telescope to discover the clear underground lake, the Arc-en-Terre and the mineral collection.
We often forget that beneath our feet lies an incredibly rich heritage! Celebrating its 30th anniversary in 2024, this underground museum for young and old offers a fascinating insight into the world of geology. With its educational sound-and-light tour 30 meters below ground and 400 meters of excavated galleries, visitors can discover the lake room, the chasm, and the slate room, where traces of the extraction of Caumont’s "blue gold" can be seen.

Message from Management
Located in Caumont-sur-Aure, the Souterroscope des Ardoisières is a tourist site offering a fabulous journey underground. Here, enter the skin of a miner and discover four large underground rooms. In the first room, the water table is explained and illustrated by a film on the water cycle. The second room houses a marvelous play of water and light, symbolizing the pact established between man and the mine. The third room teaches the extraction of slate "the blue gold of Caumont". As for the last room, the room of Wonders, it allows you to admire an extraordinary collection of giant crystals and semi-precious stones. A great address for the curious!
