Chapultepec Zoo, zoo located in Mexico City on the original site of Montezuma’s game reserve. Opened in 1926, the zoo is administered by the municipal government. Its grounds cover 13.5 hectares (33 acres) and house nearly 2,000 specimens of about 280 species, mostly in Victorian-style caging. The zoo specializes in hoofed stock and hippopotamuses. It had a pair of giant pandas and is one of the few zoos outside China to have successfully bred the animals.
