Tiergarten Schönbrunn or Zoo Vienna is a zoo located on the grounds of the famous Schönbrunn Palace. Founded as an imperial menagerie in 1752, it is the oldest zoo in the world. The still preserved buildings of the baroque era, which have been complemented in the last years by elements of modern zoo architecture, convey still a good impression of the 18th century menagerie-buildings after the Versailles model.
