c) Philadelphia Zoo

The Philadelphia Zoo, opened in 1874, holds the distinction of being the first American zoo. Its establishment marked a significant moment in the cultural and scientific development of the United States, offering a new form of public education and recreation. The zoo not only provided a place for the public to see and learn about animals from around the world but also played a critical role in wildlife conservation and research. Its opening in Philadelphia, a city with a rich history in American science and education, further solidified the zoo’s importance as an institution for both public engagement and scientific inquiry.
