Founded in 1752 as a menagerie by Franz Stephan, the Schönbrunn Tiergarten is the oldest zoo in the world. It houses some 750 animals of all shapes and sizes, including giant pandas, emus, armadillos and Siberian tigers. The zoo’s layout fans out like the spokes of a bicycle wheel, with an octagonal pavilion at its centre. The pavilion dates from 1759 and was used as the imperial breakfast room. Feeding times are staggered throughout the day – maps tell you who’s dining when.
