Saint-Nazaire submarine base
Saint-Nazaire submarine base, Maritime museum in Saint-Nazaire, France.
The reinforced concrete structure extends 300 meters in length, 130 meters in width, and reaches a height of 18 meters along the Atlantic coast.
German forces constructed this submarine shelter between 1941 and 1942, using 500,000 cubic meters of concrete to create fourteen submarine storage compartments.
The facility now houses multiple exhibition spaces, including Escal'Atlantic museum dedicated to ocean liners and LiFE contemporary art gallery inside former submarine pens.
The tourist information center within the submarine base provides guided tours in French through narrow walkways and access to the panoramic rooftop platform.
Eight submarine pens functioned as dry docks while six additional berths remained filled with water for German U-boats during World War II operations.
