Siegfried Line Museum, Pirmasens, Military museum in Niedersimten, Pirmasens, Germany.
The Siegfried Line Museum occupies a former subterranean military fortification with extensive tunnels carved into rock, displaying weapons, equipment, and historical objects from wartime. The complex extends for considerable distances beneath the ground with multiple gallery sections.
Construction of the Gerstfeldhöhe fortification began in 1938 as part of the Siegfried Line defense system built into the rock. After the war, occupation forces adapted the facility for storage and other purposes before it became a museum.
The museum presents reconstructed soldiers' living spaces and working areas as they appeared during wartime, helping visitors understand daily life in these underground bunkers. These displays show how troops adapted to confined conditions deep below the surface.
Visitors should prepare for cool underground conditions, as the tunnels maintain temperatures around 8 degrees Celsius year-round. Exploring the site with a guide provides the best understanding of the complex tunnel system and its layout.
The tunnel walls still bear messages and marks left by American soldiers who used the facility as storage space until the 1990s. These handwritten inscriptions offer glimpses into the lives and thoughts of troops who occupied these spaces decades after the war.
