Tierpark Hellabrunn is one of Europe’s foremost zoos. There are approximately 19,000 animals representing 775 species on the 99 acre property. Unlike typical zoos, most of the animals are not caged. They roam on natural habitat arranged by their native geography across seven continents (called a Geo-zoo). The Asian elephants are especially popular. The Elephant House (Elefantenhaus) was constructed in 1914, three years after the zoo opened. Hellabrunn also has active conservation and breeding programs, especially among endangered species.
