The Philadelphia Zoo was the first true zoo in the U.S. and was chartered by the Commonwealth of Pennsylvania on March 21, 1859, but the Civil War delayed its opening until July 1, 1874. One of the premier zoos in the world for breeding animals, the zoo works with many groups worldwide to protect the animals natural habitats. The 42-acre zoo is home to more than 1,300 rare and endangered animals and features a children's zoo, a paddleboat lake, a rainforest themed carousel, and interactive and educational exhibits.
