The home of William Paca, a signer of the Declaration of Independence and a governor of Maryland, this estate was built between 1763 and 1765 and restored by Historic Annapolis. It's one of two such houses in town (another, the Brice House, is around the corner but isn't open to the public). The five-part structure is composed of a central block, flanked symmetrically with hyphens and wings. The 45-minute house tour (every half-hour, last one at 3:30pm) offers a glimpse of life during Annapolis's "golden age." One exhibit focuses on a child's sickroom; another features Colonial leisure activities. The 2 acres of formal gardens feature a pond crossed by a Chinese Chippendale bridge and a two-story summerhouse. Climb to the top for a bird's-eye view of your surroundings. If your time is limited, at least see the gardens.
