In 1908 a group of civic-minded, Allen County citizens formed and incorporated the Allen County Historical and Archaeological Society. Their purpose was to collect and preserve the tangible evidence of Allen County’s remarkable history and to share those collections with the community for the betterment of its citizens. The Allen County Commissioners provided space and operational support for this purpose in the newly built Veterans Memorial Hall. Thus began the partnership between the county and the private non-profit Allen County Historical Society.

The current facility at 620 West Market Street was constructed in 1954-55. The facility was expanded in 1976, 2007, and 2010. With the exception of the ‘76 addition, all funding to build and expand the Museum was privately raised by the Allen County Historical Society.



The mission of the Allen County Historical Society is to collect, preserve and interpret the history of Allen County and Ohio as well as other areas of interest that will benefit the public served.
