It was built by Simeon Martin on his family's property and is also known as Horton Farm.","why_significant":"The nomination argues the house is architecturally significant as the only Federal mansion in Seekonk, a city-style mansion in a rural farm setting, with preserved interior woodwork and cornice and chair-rail moldings described as unique to it. It is historically significant for Simeon Martin, who served as Lieutenant Governor of Rhode Island, and his father Silvanus, a Rehoboth selectman.","narrative":"Set atop Chestnut Hill in Seekonk, this five-bay Federal mansion was built around 1799 by Simeon Martin on the family land where he grew up. It looks over farmland and the Palmer River. The frame is hand-hewn pegged oak, and the exterior includes a hip roof, a Doric-columned entrance porch, a fanlight, and a Palladian stairwell window. Inside, the central-hall plan with eight rooms retains its original woodwork, including fluted mantels and Chinese-influenced cornice and chair-rail moldings. The exterior changed in 1880, when a veranda and kitchen ell were added, and again in 1957, when the original dormers, a roof monitor and a balustrade were removed. The architect and craftsmen are unknown, though the house resembles Federal mansions in Newport. It is considered the only Federal mansion in Seekonk. Martin served as Rhode Island's Adjutant General, Major General and Lieutenant Governor, and returned to the house in 1816, living there until his death in 1819.","period_of_significance":"1799 and 1880 (18th and 19th centuries)","architect_builder":null,"architectural_style":"Federal","criteria":[],"status_note":"Listed in good condition; altered on the exterior, with the interior intact.
