Fort Frederick, originally built during the French and Indian War, was reactivated during the Revolution as a prison camp. British and German prisoners captured in the northern campaigns were confined within its stone walls. The officers’ quarters supported the administration and guarding of this important Maryland detention site. Before you is the foundation of “The Governor’s House,” the building that served as the officers’ quarters, ceremonial hall and storeroom for Fort Frederick. What did that building look like? We know the size and general layout of the building from the foundation. There are only a few historical documents, which mention the building. Of those, the most significant is Samuel Hughes’s 1778 letter, from which we learn that the building was a 2-story timber framed structure with weather board siding and a wood-shingled roof. Beyond that general description we know very little. There are no plans, sketches or early images showing more.
