Berlin Zoological Garden

During World War II, the zoo area was completely destroyed and only 91 of 3,715 animals survived, including two lions, two hyenas, an Asian bull elephant, a hippo bull, ten hamadryas baboons, a chimpanzee, and a black stork. By the end of the war, the zoo was fortified with the Zoo flak tower, a huge flak tower that was one of the last remaining areas of German resistance against the Red Army, with its bunkers and anti-aircraft weapons defending against allied air forces. Following the zoo's destruction, it and the associated Aquarium was reconstructed on the most modern principles so as to display the animals in as close to their natural environment as feasible. The success achieved in breeding animals, including some rare species, demonstrates the efficacy of these new methods.[citation needed ]
