Historic Hill is a lovely stroll through one of the oldest parts of the Saint Louis Zoo. From the 1904 Flight Cage to the Spanish architectural flavor of the 1920s in the Bird House, Primate House and Herpetarium to the finishing touches of our thoroughly modern exhibits, this area of the Zoo has a unique ambiance and a nostalgic history that make it a great destination.
