What is the difference between the North Caves and the Zonneberg Caves?
Both caves are a part of the big tunnel system in the hill of mount Sint Pieter. The entrances are at different locations. There are daily tours in the North Caves and this entrance is closest to the city center (Address: Luikerweg 71). You can reach the entrance of the Zonneberg Caves (Address: Slavante 1) by car or boat (Rederij Stiphout. There are tours in English at this location every day in the Dutch summer holiday (check for specific dates under “Zonneberg Caves”).
 
Both tunnel systems are formed by mining (former limestone mine). The stones were used as a building material. In total 20,000 tunnels were made this way of which 8,000 are still intact.
 
A big part of both tours is more or less the same. But there are also some differences. Both systems have some unique features:

  • The Kluis (Vault), was used to store famous paintings during WW2 in the North Caves.
  • The remains of the big evacuation plan from WW2 are still visible at the Zonneberg Caves.
  • The big explosion dome where the French tried to blow up Fort Sint Pieter is in the North Caves.
  • The remains of the 18th century shelter are visible at the North Caves.

Note: The tour guide has to make a selection from all of the interesting sight to see in the cave every tour. If you would like to see a specific feature; please ask your tour guide at the start of the tour.
