History

Established in 1932, Trailside Museum served as the first public nature education facility for the Forest Preserves.

Trailside Museum of Natural History is set within a historic 1876 mansion. The building has served many purposes through the years including being a residence and even housing two schools. In 1919, the Forest Preserves purchased the building, having already bought much of the surrounding land. The mansion served as the Forest Preserves’ headquarters until 1932, when the Board of Commissioners voted to make it a “trail side” museum displaying “every plant and animal in Cook County, live or mounted, for the education of the public.”
