Built between 1787 and 1788 by a merchant from Portsmouth, New Hampshire, this National Historic Landmark is a little-altered and high quality late Georgian country house. Acquired by preservationist friends of South Berwick native Sarah Orne Jewett at the turn of the 20th century, it is now a historic house museum owned by Historic New England, open for tours between June and October.Description and historyThe Hamilton House is set on 50acre of land overlooking the Salmon Falls River, the border between South Berwick and Rollinsford, New Hampshire. It is a 2-1/2 story wood frame building, with a hip roof, clapboard siding, four brick chimneys symmetrically placed in its outside walls, and gabled dormers on all four elevations. It has entrances on its north, south, and east sides, each flanked by pilasters and topped by a gabled pediment; that on the north side has a more elaborate treatment, with sidelight windows and a second pair of pilasters. On the north and east facades, there are Palladian windows above the entrances.The interior of the house follows a center-hall plan, with a wide central hall decorated with wallpaper that is a reproduction (made in 1900) of older wallpaper found in the house. The two parlor chambers and dining room have mahogany window seats, paneled chimney surrounds, and folding inside window shutters. The dining room and south parlor have wallpaper painted in 1900 by George Porter Fernald.
