Character of Denée
Carrière de La Bosse near Denée (Anhée municipality) is a former underground black-marble quarry. Its spacious extraction galleries and remaining stone pillars reflect its mining history.
The flooded workings form a full overhead environment. Mining remnants, sediment and possible instability require particular caution.
