1. Baboon Island Marker
Inscription. This site was the former home of our Baboon Island exhibit. Opened in the mid-1930s, the exhibit, originally called Monkey Island, housed hundreds of different species throughout its tenure. This man-made mountain, a first of its kind in the U.S., replicated the natural habitat of the monkeys, giving people a barless, naturalistic view of the animals and their native homes that was carried throughout our grounds.

Renowned Chicago Architect Edwin H. Clark designed the original buildings on Brookfield Zoo grounds after traveling throughout Europe and studying the naturalistic, barless exhibits there. He used his architectural skills to calculate exhibit depth and slope to ensure Brookfield Zoo's animal residents couldn't wander, or leap, away.

In order to replicate the topography of an animals' exotic home, he relied on John Hurlimann, an influential Swiss artist and sculptor, to recreate the mountains and valleys of habitats in the wild. Hurlimann used gunite, a sprayable concrete mixture, to mimic the home of monkeys living on the former Baboon Island. The innovative use of gunite not only allowed guests to view the animals in the most naturalistic way available, but it gave the animals an area to explore in a more natural setting.
