The Beijing Zoo Amphibian Reptile Pavilion is located in the southwest of the zoo. Built in 1979, with a construction area of 4,345 m², it used to be one of the best pavilions in Beijing Zoo. The amphibian reptile pavilion is divided into two floors, with more than 90 exhibition rooms of different sizes set up in the pavilion.
