It contains three historic houses, a barn, stone walls and other farm landscape features.","why_significant":"The land was farmed by members of a single family, the Knowles family and relatives by marriage, the Pennimans, from 1742 to 1943. The district preserves a rare surviving agricultural landscape, including the Second Empire Penniman House, Georgian and Greek Revival houses, and stone walls unusual on Cape Cod. It also includes land with Native American archaeological significance tied to the early 1600s contact period.","narrative":"Fort Hill is a roughly 100-acre stretch of fields, woods and salt marsh in Eastham, on the eastern side of Cape Cod, with wide views over Nauset Marsh toward the Atlantic. Two farmsteads, held by the Knowles family and their in-laws the Pennimans, occupied the land without interruption from 1742 to 1943. Three historic houses stand close together along Fort Hill Road: the Second Empire Captain Edward Penniman House of about 1868 with its whalebone gate and barn, the Greek Revival Sylvanus Knowles House of about 1864, and the Georgian Seth Knowles House of about 1790. Stone walls, foundations, property markers and open fields complete the farm landscape, and the walls are rare on Cape Cod. The area also holds a large prehistoric site, and Samuel de Champlain described cleared, inhabited land here in 1605. Creation of the Cape Cod National Seashore in 1961 limited later change while the surrounding region developed.","period_of_significance":null,"architect_builder":null,"architectural_style":"Late Victorian: Second Empire; Mid 19th Century: Greek Revival; Colonial: Georgian","criteria":[],"status_note":"The National Park Service owns most of the land and structures, and two historic houses are privately owned.
