1800s
Glen Oak Zoo had it's beginnings in the late 1800's when a herd of elk was donated to the Peoria Park District.  Over the next fifty years, the "zoo" moved to several locations, eventually near the lagoon in Glen Oak Park.

1955
In order to develop a more formal collection, advice was sought from Marlin Perkins, Director of the St. Louis Zoo and later star of Mutual of Omaha's Wild Kingdom, and local architect Cletis Foley.  The current Glen Oak Zoo exhibits building opened in 1955.

1970s
The Zoo took on a more professional appearance, emphasizing education, conservation and recreation.

1976
In it's ongoing commitment to provide a quality attraction where people of all ages could appreciate the wonders of nature, Glen Oak Zoo became an accredited member of the American Zoo and Aquarium Association.  Friends of Glen Oak Zoo was formed and collaborated with the Peoria Park District to offer new animals and exhibits.

1992
A community task force was formed to analyze the Zoo's status and recommend a path regarding it's future.  The conclusions: the zoo is an important part of our community; it should remain centrally located; a master plan should be developed to give direction.

1997
The Peoria Zoological Society was formed to lead the effort for the new Zoo.  Torre Design Consortium was hired and after significant community involvement, a Master Plan was completed and adopted.

2002
The Peoria Park District and the Peoria Zoological Society signed an agreement regarding the expansion of the Zoo and fundraising efforts began.
