The mine has been there since 1860, and was one of many build to extract the plenty of coal reserves there. The main building is composed of a gothic castle which looks like a winding tower with bathrooms and other facilities.
It was abandoned in 1977. If you just look the outside, it's not clear if it's an industrial complex or an ancient castle, however, when you get inside, you can see the rusty mine machines, footbridges and stairs.
If you get to the top of the tower, you'll have a panoramic view of Charette and the rest of the complex, as of the machines for heavy mining.
Lamentably, most of the other buildings are empty, with some exceptions. However, the rest of the place still offers an interesting architecture and an opportunity for great photos.
