Located on the grounds of the imperial summer palace, Tiergarten Schönbrunn (Vienna Zoo) is the oldest zoo in the world - and yet still frequently voted one of the world's best. The zoo was founded as an imperial menagerie in 1752, by the then Holy Roman Emperor, Francis I. It was opened to the public in 1779. The Tiergarten has an amazing array of animals (more than 700 species in all).
