Where is the oldest ZOO in the world?
The zoo was constructed in 1752 next to Schloss Schönbrunn by Adrian van Stekhoven at the order of the then Holy Roman Emperor, Francis I, husband of Maria Theresia, to serve as an imperial menagerie and is the oldest continuously operating zoo in the world. It was centered around a pavilion meant for imperial breakfasts. Therefore, thirteen animal enclosures in the form of cut cake pieces were established around this central pavilion.
