The St. Mary’s County Museum Division was established by the Commissioners of St. Mary’s County to collect, preserve, research and interpret the historic sites and artifacts which illustrate the natural and cultural histories of St. Mary’s County and the Potomac River. These sites include St. Clement’s Island Museum, Piney Point Lighthouse Museum, the Old Jail Museum and the Drayden African American Schoolhouse. With this as its charter, the Museum Division serves as a resource, liaison and community advocate for all St. Mary’s County public and private cultural assets.
