Closed since 1987, this former cement stone quarry is one of the most important in the region where it is located, in East France.
Unfortunately a lot of information about this quarry has been lost, and we don't currently know its size. Some explorers have told me that they have managed to cover 50km of the underground tunnels for the moment, across several floors.
