To get an insight into the town’s long coal-mining heritage, don a safety helmet and take the cage down into the murky tunnels of this disused mine, once used to train apprentice colliers. The one-hour guided tour explores 700m of galleries. The tour and introductory video are in French, but an English guidebook is available. Above ground, there are various industrial relics relating to the coal extraction process.
Wear something warm, since the temperature underground never tops 16°C.
