a building with a rich history, right in the heart of Painesville

The office building has been designated by the Lake County Historical Society as a Historic Marker, meaning a structure of significance to the history of Lake County. Around 1843 a framed tavern house was built on the property, and then in 1905, construction started on the present building, which at that time was the Salvation Army’s Citadel for Lake County. The exterior of the building has changed very little since 1905.
