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 that arrived in 2003. A batch of emus, armadillos and baby Siberian tigers joined them in 2006. Thankfully most of the original cramped cages have been updated and improved. The zoo’s layout is reminiscent of a bicycle wheel, with pathways as spokes and 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 on display tell you who’s dining when.
