Zonneberg Caves
Grotten Zonneberg
Another marlstone tunnel system on the east side of Mount Saint Pietersberg, known for its World War II shelter remains and walls covered in charcoal drawings.
The Zonneberg tunnels lie on the Meuse side of Mount Saint Pietersberg. During World War II they were converted into an air-raid shelter able to hold the entire city's population. Remains of a well, a bakery, and a small chapel survive. The walls are covered with many 18th- to 20th-century charcoal drawings and advertising images. Visits are by guided tour only and last about one hour. There are fewer time slots than at the North Caves. Tours run mainly in warm months and on holidays, and you can reach the caves from the old town by river cruise.
