The Blueprint Collection consists of blueprints, plans, architectural, and landscape drawings of Corona area buildings. Included in the collection are the original blueprints of the Woman’s Improvement Club, the historic Corona Civic Center, Corona Public Library, and the architectural drawings created by local architect Leo Kroonen for the 1912 Corona City Hall. Not all regional buildings are represented in the collection.

Detailed information on the blueprints may be difficult to read on the digital images provided on Corona Heritage Online. However, the Blueprint Collection is available for viewing during normal Heritage Room hours.
