Caves North (Sint-Pietersberg)
Grotten Noord
A network of underground galleries left by centuries of marlstone mining. Charcoal drawings and signatures by past miners and refugees cover the walls.
Mount Saint Pietersberg has been mined for marlstone since the Middle Ages, leaving thousands of tunnels underground. During the war they were also used to hide people and artworks. The Rembrandt painting The Night Watch was stored in the mountain during World War II. Visits are by guided tour only and last about one hour. The caves have no lighting, and the guide carries a lamp while explaining the charcoal drawings, bats, and fossils on the walls. English-language tours are available. Book online in advance during peak season. The cave stays around 10°C year-round, so bring a jacket and non-slip shoes.
