Philadelphia Zoo

The Philadelphia Zoo is a zoo located in the Centennial District of Philadelphia on the west bank of the Schuylkill River. It was the first true zoo in the United States; it was chartered by the Commonwealth of Pennsylvania on March 21, 1859, but its opening was delayed by the Civil War until July 1, 1874. The zoo opened with 1,000 animals and an admission price of 25 cents. For a brief time, the zoo also housed animals brought to U.S. from safaris by the Smithsonian Institution, which had not yet built its National Zoo.

The Philadelphia Zoo is one of the premier zoos in the world for breeding animals that are difficult to breed in captivity. The zoo also works with many groups around the world to protect the natural habitats of the animals in their care.

The zoo is 42 acres (17 ha) and the home of nearly 1,300 animals, many of which are rare and endangered. Special features include a children's petting zoo, a rainforest themed carousel, a climbing structure, chats with keepers, behind the scenes tours available for purchase, and many interactive and educational exhibits.
