Underground quarries of the Malogne

The Underground Quarries of Malogne extend across 68 hectares beneath Cuesmes, featuring a complex network of tunnels created through room and pillar mining methods.

Mining operations commenced in 1877 with the Rolland quarry extraction site, continuing through multiple operational phases until the final closure in 1958.

The Faculty of Polytechnique in Mons uses sections of these quarries for educational purposes, teaching students about geological formations and mining techniques.

Tours require groups of minimum 20 participants, with visitors needing to bring personal lighting equipment to navigate through the underground passages.

The quarry walls contain preserved fossils from the Cretaceous period, including mosasaurus teeth, belemnites, oysters, and turtle remains.
