Artilleriewerk Grimsel, Military fortress at Grimsel Pass, Switzerland
The fortress extends through a one-kilometer tunnel system carved into the mountain, containing barracks, medical facilities, and artillery positions at 2000 meters elevation.
Built between 1941 and 1943, this artillery fortress formed part of the western defense zone of the Gotthard Fortress during World War II.
The facility demonstrates Swiss military engineering excellence through its integration of defense capabilities with mountain terrain and hydroelectric infrastructure.
Access to the fortress was provided by a 700-step underground stairway and a cable car system that could transport 25 people at once.
The fortress housed six 15-centimeter bunker cannons with separate batteries covering different strategic sectors toward Italy and the Gotthard region.
