Caves of St Pietersberg

Do you dare go underground? Not afraid of the dark? Go exploring in the caves below the St. Pietersberg hill. No light, no sound, no smell, no radiation, no pollution, no mobile phone signal, no idea of time…Over the centuries, the mining of marl in the caves has created a labyrinth of more than 20,000 tunnels. 'Block breakers' and artists alike have left their marks here. The caves also served as a refuge for the people of Maastricht during the many sieges of the city, including during the Second World War.

Between 1575 and 1825, a network of underground passageways or mine galleries was created on the western side of Maastricht. In times of siege, these tunnels were used to surprise the enemy from underground. During the Second World War, the people of Maastricht spent many anxious hours here sheltering from the bombardments. Visit the vaulted chambers, powder rooms, and imposing bombproof shelters, and learn more about this unique monument of military engineering. You can also see the above-ground and underground fortifications in a single tour. The Fortifications Maastricht Foundation has developed two different tours to show you them: the Du Moulin Line tour and the Long Kazematten Walk.
