This early-American building outside Washington, across from the town's small airport, is designed to illustrate life in the various periods of history of the area. A working plantation, the complex includes a redbrick Greek Revival mansion from 1869. There's also a gray-framed "Federal plainstyle" house circa 1790, with period furnishings. Exhibits include the old kitchen, a formal parlor, and a dignified but rather bleak series of upstairs bedrooms. Accompanied by a local guide, you can also visit several outbuildings.
