Zoological Society of Philadelphia

The Philadelphia Zoo’s 42-acre garden is home to more than 1,300 animals, many of them rare and endangered. By connecting people with wildlife, the Philadelphia Zoo creates joyful discovery and inspires action for animals and habitats.

The Zoo opened its gates on July 1, 1874. The Frank Furness Victorian gates and gatehouses, and the Zoo’s location, are the same today as they were on the day it opened.

In its first year of operation, the Philadelphia Zoo had 813 animals and received well over 228,000 visitors. Today, the Zoo has more than 1,300 rare and endangered animals, and its attendance is approximately 1.35 million visitors a year.
