The Baghdad Zoo is a 200-acre (81 ha) zoo originally opened in 1971 and located in Baghdad, Iraq, in the al-Zawraa' Gardens area along with the Zawraa Amusement Park and Zawraa' Tower. Before the 2003 invasion of Iraq, the zoo housed 650 animals. Saddam closed it for renovation in 2002 and, after being decimated during the 2003 Iraqi war, when only about 35 animals survived, it was intended to reopen in April 2003 after a $50 million facelift. The zoo reopened in July 2003, three months after the invasion. The zoo falls into what is known as the "green" zone, an area that contains most of Saddam Hussein's city palaces and government departments, and which is under heavy US security. As of May 2003 there were about 50 animals, mostly big cats and other carnivores which had been collected at the Baghdad Zoo from four other collections, one public and three private, which had been identified from around the city.
