Zoo Tower

The Zoo flak tower was a fortified flak tower that existed in Berlin from 1941 to 1947. It was one of several flak towers that protected Berlin from Allied bomber raids. Its primary role was as a gun platform to protect the government building district of Berlin, in addition the Hochbunker was designed to be used as a civilian air-raid shelter. It also contained a hospital and a radio transmitter for use by the German leadership, and provided secure storage facilities for art treasures.
During the Battle of Berlin, it acted as a citadel and by depressing its large anti-aircraft artillery, its garrison was able to provide support for ground operations against Soviet Red Army.
