Underground Tunnels

Built between 1575 and 1825, Maastricht’s nearly 9 miles of underground tunnels played a crucial role in the city’s history. Originally constructed to store arms and to serve as a bunker for troops during times of invasion, the subterranean network, which runs along the city’s walls, was used as a shelter for locals during World War II and Cold War. During the course of WWII, nearly 800 artworks were stored here, including Rembrandt’s iconic Night Watch. Indagare members can contact our Bookings Team to arrange a guided tour.
