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.

Despite serious discussions dealing with a possible closure of the park, the 1990s saw a process of replacing improvised or damaged structures as well as expanding the zoo with new areas for African ungulates and primates, as well as species from alpine regions of Asia and Europe.
