The Greene County Heritage Museum chronicles the full sweep of the county's history from Cherokee occupation through the deeply divided Civil War — where Greene County produced soldiers for both armies — to its 20th-century agricultural and industrial development. Exhibits feature Civil War artifacts, Reconstruction-era political documents, and items related to the county's extraordinary presidential heritage as home of Andrew Johnson. Rotating exhibitions explore specific topics including the county's remarkable railroad history and natural heritage. An excellent starting point for exploring Greeneville's historic district.
