The house grew in stages from a farmhouse built by Washington's father Augustine, probably in the 1730s, to its final form in 1787.","why_significant":"The nomination argues that Mount Vernon was the home of George Washington, general, statesman and first President of the United States. It was his main occupation as a planter before the Revolution, his home through his military and political career, and his place of retirement and burial.","narrative":"Mount Vernon, on the Potomac about seven miles south of Alexandria, Virginia, was the home of George Washington. The mansion is a Georgian house with a high-columned, two-story piazza facing the river, a pedimented west front, a modillion cornice and an octagonal cupola added in 1787. It grew over time. Augustine Washington probably built the first portion in the 1730s. George Washington rebuilt it in 1757-58 and enlarged it to 2 1/2 stories. During the Revolution his kinsman Lund Washington widened the house from five to nine bays, added the piazza and flanking wings, and extended the gardens. The estate includes restored outbuildings, gardens, a bowling green, a greenhouse and the tombs of George and Martha Washington. The nomination treats it as significant because Washington farmed here, lived here through his military and political career, retired here in 1797 and died here in 1799. About 400 acres are nominated.","period_of_significance":"1752-1799","architect_builder":"Augustine Washington (probably built the first portion); George Washington (rebuilt 1757-58, cupola 1787); William Fairfax (supervised 1757-58 construction); Lund Washington (enlarged the house during the Revolution)","architectural_style":"Georgian","criteria":[],"status_note":"Occupied and used as a museum; owned by the Mount Vernon Ladies' Association.
