The Royall House was purchased in 1732 by Isaac Royall, a wealthy merchant of Antigua, and extensively remodeled in the period 1733-37. He added a full third story to the original house and encased the east facade in clapboard, ornamenting the exterior with profuse architectural details in wood. Rented by the Daughters of the American Revolution in 1896, and acquired by the present owners 12 years later, the Royall House has received expert treatment in recent years in the restoration of interior colors, furnishings, and wallpapers.
