U-Boot-Bunker Finkenwerder, World War II submarine bunker in Finkenwerder, Germany.
The U-Boot-Bunker Finkenwerder was a reinforced concrete shelter measuring 232 meters long and 160 meters wide, with a roof 3.6 meters thick designed to protect submarines. Today, you can see partially excavated foundation walls marked with black gravel that outline where the complex once stood.
Construction started in March 1941 and continued until 1944, with the facility designed to shelter up to 15 submarines. After demolition in 1946, the bunker lay buried until 2002, when work at the Airbus facility brought it back to light.
The site displays memorial plaques and information about the forced laborers and concentration camp prisoners who were made to work on its construction. These marks tell a story about the human cost of the war that remains visible today.
The site is partially walkable and shows the excavated outlines of the bunker structure. Wear comfortable shoes as the ground can be uneven, and the gravel markings only outline where the structure once existed.
The site is now protected as a monument and sits right next to the Airbus facility, where the bunker was accidentally rediscovered during construction work. Walking from modern aircraft production to this wartime relic creates an unexpected contrast.
