St Louis Zoo

Since its very beginning, the Saint Louis Zoo has 
been a leader in exhibit design. With the world's largest 
walk-through bird cage built for the World's Fair of 
1904 and the open moated bear pits built in 1924, the 
Zoo combined good animal care with natural settings. 

In the 1902s the Primate House, Bird House and 
Herpetarium were built on Historic Hill in Spanish-
style architecture, with elaborate architectural details 
and open atriums filled with tropical plants. Even 
simple exhibits like the woodsy Chain of Lakes or the 
rocky burrows of the prairie dogs give visitors a unique 
glimpse of nature.
