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 1954-1955. The facility was expanded in 1976, 2007, and 2010. With the exception of the 1976 addition, all funding to build and expand the Museum was privately raised by the Allen County Historical Society.

The Allen County Museum is currently not collecting items as we are rearranging collections storage, updating our collecting policies, and continuing to process our existing collections. If you have any questions, please contact Rachel Johnston at rjohnston@allencountymuseum.org or 419-222-9426.

The Museum belongs to you, the citizens of Allen County. The original property was deeded to the county by the William Wemmer family with the express purpose of being the locale of the Museum. Over the years the Historical Society bought all surrounding property on High and Metcalf Streets and subsequently deeded the property to the county. One exception to this is the MacDonell House which is owned by the Historical Society.

The collections belong to the Allen County Historical Society. A small number of currently exhibited items are on loan to the Museum. And, some public records are on permanent loan including naturalization records and others used by local and family history researchers.

The vast majority of the 280,000 collection items housed at the Allen County Museum were donated by the citizenry of Allen County. For more than 100 years, Allen County citizens have donated their prized family heirlooms with the intent that these items be shared with future generations who would be educated about, and find pride in, their heritage.

The Museum is governed under bylaws that were mutually developed and agreed upon by the Allen County Commissioners and the Board of the Allen County Historical Society in 1980. The bylaws establish that the operation of the Museum is vested in the policies and procedures set forth by the Board of the Allen County Historical Society. The day-to-day operations of the Museum are carried out by the Museum staff, who are county employees as established by the bylaws and personnel policies.

The Museum is a department of county government and funded by the county’s general fund. Currently, funds appropriated to the Museum cover staff wages, health benefits where applicable, and OPERS retirement. Prior to the recession of 2008, the Museum’s appropriation also included funds for supplies, service contracts, and travel.

The Allen County Historical Society also funds the Museum’s operation. The Society funds all exhibit and collections related items, all programs, supplies, service contracts, a portion of the property maintenance, and Historical Society employees. The Historical Society also provides all funding for the operation and maintenance of the historic MacDonell House.

The Museum serves more than 60,000 visitors annually including:

• Children and teachers from Allen County and surrounding counties

• Families, primarily from Allen County, but also other areas

• Adults and families that attend programs, concerts, demonstrations and events at the museum including the very popular Christmas Tree Festival

• General visitors from the area, state of Ohio, and virtually every state in the Union

• Genealogists, local history researchers, attorneys, and preservationists from diverse locations that utilize the museum’s library and archives

• Railroad history researchers from all over the world

The founders of the Historical Society and Museum, including elected officials, believed that a community’s history belongs to everyone and should be accessible to all who seek to benefit from it. While some people have suggested that the Allen County Museum could significantly increase its revenues by charging admission, research reveals that even the largest museums struggle to achieve 10% of their operating expenses from admissions. Further, since the recession of 2008, more and more museums have stopped charging admission preferring to adopt actively marketed “goodwill contribution” policies. And finally, the Allen County Museum led a daylong session with focus groups to study this issue. The conclusion, based on participant opinion, was that the Museum should not charge admission.

The Museum has a suggested donation of $5 per person to visit the museum. Many visitors donate more than the suggested amount. There is a $3 admission charge for adults to visit the MacDonell House; members of the historical society are admitted for free.

The Allen County Museum and Historical Society has been the community’s anchor for more than 100 years.

The Allen County Museum is the number one attraction in Allen County according to the Lima-Allen County Convention and Visitor’s Bureau.

Congressman Jim Jordan nominated the Allen County Museum for a National Medal for Museum and Library Service.

The Allen County Museum was named a “Standout in Ohio Tourism” by the Ohio Traveler.

The Allen County Museum was featured in the WBGU-PBS documentary entitled, “Made in America: the Lima Locomotive Works.”

The Allen County Museum was featured in an episode of “What’s in the Barn?” on the Velocity Channel and the Discovery Channel. Plus, the highly prized Thor motorcycle traveled to the prestigious Amelia Island Concours D’Elegance International Auto Show in Florida where it won top honors for “Provenance and Originality,” and most “Historically Significant” machine in the motorcycle class.

The Allen County Museum is the only county museum in the state of Ohio that is accredited by the American Alliance of Museums, (the national association that sets standards of excellence for all museums), and one of only 1,000 (out of 20,000) in the entire country to hold that distinction.
