About The Berlin Flak Tower
The Berlin Flak Tower in Humboldthain Park is a seven storey bunker originally built under Hitler’s orders to protect Berlin from aerial attacks during the Second World War. In fact, in 1940, Hitler planned to build six such flak towers.
Three flak towers were constructed and, after the war, the only Berlin Flak Tower to survive was the Humboldthain tower. The rest were destroyed and even the surviving Berlin Flak Tower has suffered severe damage.
During World War II the lower floors of the Berlin Flak Tower were also used as a bomb shelter for thousands of the city’s population. Only two floors are currently open to the public and 90 minute tours are provided by the Berlin Underground Association.
If you go, ensure to wear comfortable shoes and plenty of layers as it can get quite cold (even in summer). Visitors must be at least 14 years of age and under 18’s must be accompanied by an adult.
