Review:

Maastricht’s Casemates is a nine-mile network of defensive bunkers, mine galleries, and tunnels that were built between 1575 and 1825 on the western side of Maastricht as part of the city’s defense system. These tunnels were used to approach and surprise the enemy from underground when the city was under siege up until the 18th century and later as shelter from bombardments during the Second World War. Visitors can explore the tunnel system and vaulted chambers, which has been hailed as a monument to the art of war, on guided tours.
