Edinburgh Zoo, formerly the Scottish National Zoological Park, is an 82-acre (33 ha) non-profit zoological park in Corstorphine, a suburb of Edinburgh, the capital of Scotland. The land lies on the south facing slopes of Corstorphine Hill, from which it provides extensive views of the city. Built in 1913, and owned by the Royal Zoological Society of Scotland, it receives over 600,000 visitors a year, which makes it Scotland’s second most popular paid-for tourist attraction, after Edinburgh Castle. As well as catering to tourists and locals, the zoo is involved in many scientific pursuits, such as captive breeding of endangered animals, researching into animal behaviour, and active participation in various conservation programs around the world.
Edinburgh Zoo was the first zoo in the world to house and to breed penguins. It is also the only zoo in Britain to house koalas and giant pandas. The zoo is a member of the British and Irish Association of Zoos and Aquariums (BIAZA), the European Association of Zoos and Aquaria (EAZA), the World Association of Zoos and Aquariums (WAZA), and the Association of Scottish Visitor Attractions. It has also been granted four stars by the Scottish Tourism Board. The zoo gardens boast one of the most diverse tree collections in the Lothians.
