Founded in 1955, it was originally established as a counterpart of the famous Berlin Zoological Garden, which was located in what was then West Berlin and soon to be out of reach for residents of the former eastern sector. The initial bear enclosures featured natural rocks and artificial waterfalls, while large paddocks surrounded by old trees and canals were designed for camels and bison. In the following years and decades, other exhibits, aviaries, and larger buildings were added to accommodate a selection of carnivores, ungulates, reptiles and birds, as well as primates, including great apes.
