Without a doubt yes. It has some beautiful old buildings in Secession archictecture, the most important being the entrance building and the elephant house.
The absolute stars are both artificial Little and Great Rock that dominate the central part of the zoo. A number of paths lead over and around these rocks, past enclosures for ungulates and predators.
Inside the Great Rock is Magic Hill, a large interactive museum about evolution, species diversity and the relationship between humans and nature.
However, most of the enclosures are only mediocre; this zoo has to rely mainly on its landscaping, (17 accessible) buildings and its large and broad collection. The latter one is particulary strong in Australian faune.
