Service Update

The majority of our Zoo experiences are available with modified service and enhanced safety protocols. Some experiences are temporarily closed for your health and safety. Please see Zoo Reservations for more information on what changes have been made for your safety. 
All guests, including Zoo members, must now reserve FREE, timed tickets prior to visiting the Saint Louis Zoo. 

When the Primate House was renovated in 1977, the original Spanish-style architecture of the 1925 structure was preserved, but the animal enclosures were completely redesigned. The traditional barred cages lining the walls were updated to large exhibits with colorful murals, rock formations, branches, ropes and live plants make it possible for monkeys and their relatives to be housed in social groups typical of their life in the wild.

Separated only by glass from active family groups, you can watch a panorama of grooming, foraging for food, playing, parenting and other social interaction. Rockscapes, waterfalls, trees and vines provide numerous footholds for climbing and jumping.
