Mount Vernon was the plantation house of George Washington, the first President of the United States, and his wife, Martha Dandridge Custis Washington.
 The estate is situated on the banks of the Potomac River in Fairfax County, Virginia, near Alexandria, across from Prince George's County, Maryland.
 The Washington family had owned land in the area since the time of Washington's great-grandfather in 1674.
 In 1739 they embarked on an expansion of the estate that continued under George Washington, who came into possession of the estate in 1754, but did not become its sole owner until 1761.
George Washington’s Gristmill was part of the original Mount Vernon plantation, constructed during the lifetime of the United States' first president.
 The original structure was destroyed about 1850.
 The Commonwealth of Virginia and the Mount Vernon Ladies’ Association have reconstructed the gristmill and the adjacent distillery.
 The reconstructed buildings are located at their original site three miles (5 km) west of Mount Vernon proper near Woodlawn Plantation in Alexandria, Virginia.
 Because the reconstructed buildings embody the distinctive characteristics of late eighteenth century methods of production and are of importance to the history of Virginia, the site is listed on the National Register of Historic Places despite the fact that the buildings are not original.
