Since 2007, the zoo, which opened on Sept. 15, 1951, has been considerably modernised. In 2000, the zoo opened a modern chimpanzee house with outdoor facilities. In 2008 a facility for wolves followed and in 2010 the massively walled 525 sqm large facility for Hokkaido brown bears. 2011 followed the renewed Reptile House.
The Asia Zone was built on the site of the former amusement park in 2012. The 10,000 sqm site includes facilities for Amur Tigers, Snow Leopards, Red Pandas, Himalyan Black Bears, Malay Bears and Gibbons. Finally, the Africa Zone was opened on 31 October 2015. Giraffes, zebras, hyenas, ostriches, lions and hippopotamuses now live in two large building complexes with outdoor facilities.
