Humboldthain Flak Tower

This anti-aircraft turret was built to protect the center of Berlin from aircraft air strikes and was built in 1940 as a military installation. There are also some private houses around the anti-aircraft turrets, which can be used as shelters and hospitals. After the war, it was bombed and abandoned for many years. It opened for tourists in 2004. Located in Humboldthain Park, it has become a good lookout point and a place worth visiting for those interested in WWII military installations.
