Underground facility built during World War II for arms manufacturing. 170 prisoners died during the construction of the underground shelter.
The Goldbach Tunnels was constructed between June 1944 and April 1945 by inmates of the Überlingen-Aufkirch concentration camp of the Dachau concentration camp under forced labor conditions. It was built into the Molasse rock formation between the village of Goldbach(de) and Überlingen on the northern shore of the Lake Überlingen. The facility was intended to serve as an underground relocation site for war-critical armaments industries from Friedrichshafen, located about 35 kilometers southeast.
