Grotten Sint Pietersberg

An underground labyrinth with over 20,000 tunnels dug out during mining activities. Miners as well as artists have left their mark here, also visible in the
form of old wall paintings. During times of siege, the caves also served as a place of refuge. The facilities dating from World War II are still partially intact.
The temperature in the caves is always 9°-10° C.
