Penhow Castle is unusual for its intimate scale. Although long known by this title, it might better be described as a fortified manor house. Unlike the large castles in Wales, Penhow has an almost unbroken history of family occupation. The 12th century keep tower dominates an ensemble which includes a 15th century hall block and the late 17th century domestic section which is visible from the old Chepstow Road.
N.B. As of July 2003 the castle is not open to the public.
