Flak towers in Berlin, Fortified defense tower at Großer Bunkerberg, Germany
The Flak towers in Berlin are massive concrete structures built between 1940 and 1944 as air defense installations, with some still visible today. They served as shelters for civilians, firing platforms for anti-aircraft guns, and storage facilities for important collections.
The project began in 1940 on orders from the Nazi leadership after British bombing raids hit the city. Additional towers were built through 1944 as part of a broader strategy to defend Berlin against air attacks.
The tower shapes how the neighborhood looks and serves as a daily reminder of Berlin's past under bombardment. Visitors see today how the city tried to protect itself and its treasures during that period.
The towers are visible from the outside, but interior access is often limited or unavailable. Those interested in exploring the history should check in advance which installation is currently accessible.
Underground chambers stored artworks and artifacts from Berlin museums during the final months of World War II to protect them from destruction. This role as an improvised art storage facility makes these towers an important chapter in the city's cultural history.
