A new outdoor enclosure for the Orangutans (2003)
was opened in July 2003. Up until then this was the largest donation by the Wuppertal Zoo Society to the Zoo. Without bars and as close as possible to a natural environment the Orangutans are provided with some 600 sqm of wonderful climbing area. Visitors get a clear view from the glass observation areas located in rock-like caves and can see the many plants and trees suitable for the animals in the enclosure. The outer walls of the enclosure have been modelled as an artificial rock face.
