Philadelphia Zoo

About America's First Zoo

The Philadelphia Zoo’s 42-acre Victorian garden is home to more than 1,300 animals, many of them rare and endangered. The Zoo, fulfilling its mission of conservation, science, education and recreation, supports and engages in conservation efforts to protect endangered species around the world. Cheetahs, hippos, giraffes and much more make the Zoo Philadelphia's leading family attraction with over 1.2 million visitors last year.

Like many other Philadelphia landmarks and institutions, the Philadelphia Zoo is an American first. The charter establishing the Zoological Society of Philadelphia was approved and signed on March 21, 1859. Due to the Civil War, however, it was another 15 years before America's first zoo was ready to open.
