Compare Brookfield Zoo and the Chicago Zoological Society

Brookfield Zoo first opened its gates to the public on July 1, 1934. The zoo has impressed millions with its barless exhibits—an innovation imported from Europe—and its expansive collection of rare and endangered species. Managed by the Chicago Zoological Society and located 14 miles west of the city's center, the zoo serves as an inspiring natural refuge for weary urbanites, while also drawing visitors from across the country with its innovative and expansive exhibits, unusual and diverse species, and gorgeous landscaping.
