Tiergarten Schönbrunn (literally, "Schönbrunn Animal Garden"), or "Vienna Zoo", is a zoo located on the grounds of the famous Schönbrunn Palace in Vienna, Austria. Founded as an imperial menagerie in 1752, it is the oldest continuously operating zoo in the world.

The conception of Vienna Zoo first came about when Emperor Franz Stephan I ordered the construction of a menagerie, with the intention of it being used exclusively by members of the royal family. 

Construction began in 1782, next door to the Imperial Summer residence, Schönbrunn Palace. In later years, when the public had been granted admission—with the request of the Emperor that they wore appropriate attire when attending—the zoo had assembled a colorful collection of birds and monkies. 



Today, Vienna Zoo has a strong reputation for its extensive and thriving collection of exotic animals, including polar bears, lions, tigers, and wolves. Features of the modern site include an aquarium, desert house, rainforest house, polarium, and bird pavilion.


Baby pandas, on loan from China, are among some of the zoo’s recent additions. Many were surprised at their births, as it is notoriously difficult to persuade Giant Pandas to breed in captivity.
