One of the most iconic spots of the city, the zoo was inaugurated by biologist Alfonso L. Herrera in 1924, inspired by the Giardino Zoológico em Museo de Zoología de Comune di Roma. During the 90’s it was totally remodeled, and the animals were redistributed in bioclimatic areas, as we can appreciate nowadays. The zoo houses 1800 animals distributed in 17 hectares, and in 1998 a breeding lab was established for the reproduction of animals in captivity. The Chapultepec Zoo provides the opportunity of getting to know and admiring wildlife species from Mexico and the world. Species from different regions are exhibited, some of them endangered, such as the giant panda; endemic species to the Cuenca de México (a basin comprised of 4 valleys) such as the Xochimilco axolotl or the volcano rabbits, also standout.
