Private tour of Grotten Noord

Dare to go completely underground and don't be afraid in the dark: go on an adventure in the cave system North in Mount Saint Peter (Mount Saint Peter)! No light, no sound, no smell, no radiation, no pollution, no reaching your phone, no sense of time. In a labyrinth of once more than 20,000 corridors, a professional guide takes the group to a depth of 30 metres.

The guided tour

As soon as the iron gate closes, the humidity rises. A maze of corridors all looking alike reveals itself. Fortunately, Maastricht Underground's guide ensures that the group does not get lost in this maze of once about 230 and now a good 80 kilometres of man-made underground passages. Names and drawings in charcoal emerge on the walls of people who worked here day in day out several hundred years ago to extract marl as a raw material. One corridor after another was cut out by these block breakers. For centuries, the Maastricht people and their valuable possessions managed to find safe shelter in the subterranean caverns of their 'mountain' in times of war. Three farming families sheltered with their livestock in Caves North. The oven where they baked bread can still be seen. There are also traces of the French siege in which attempts were made to blow up Fort Sint Pieter. Discover Maastricht's underground secrets on this impressive tour!
