George Washington’s Mount Vernon Celebrates Archaeology Month with New Discovery, Special Programs

MOUNT VERNON, VA – George Washington’s Mount Vernon celebrates Virginia Archaeology month with new programming and a special “Archaeology Day” held on Saturday, October 5! The estate’s archaeologists have also made a tremendous discovery – the foundation of Washington’s “necessary” on the east lawn. Mount Vernon will also launch its House for Families online archaeology collection this month featuring 345 objects.

Archaeologists Uncover Foundation on East Slope

This summer, Mount Vernon’s archaeologists located the remains of a building foundation—a “necessary,” or privy, on the east lawn—which was constructed during Washington’s lifetime and later removed at his direction.

Evidence of this feature can be found in Washington’s writings. In late May 1796, George Washington wrote from the presidential residence in Philadelphia to his farm manager at Mount Vernon, “I have several times spoke concerning a necessary for the Quarter People [the enslaved], at Mansion house [Farm] . . . I wish you would have this done before We come home that the yard of the Quarter may be always clean & Sweet.  If the old necessary on the brow of the Hill can be moved with more ease than building a new one, let it be done, as it is not only useless where it is but is an eye-sore.” 

A 1787 sketch of Mount Vernon’s layout depicts a necessary on the east lawn of the mansion, at the “brow of the Hill” overlooking the Potomac River. The building also appears in a view drawn by an Irish visitor in 1795.

While excavating on the east lawn this fall, in preparation for repairing the ha-ha wall, archaeologists exposed a 10 x 12-foot brick foundation in the area where this “old necessary” stood, according to the 1787 drawing. Although archaeologists do not know if the necessary was moved as Washington directed, or if a new privy was constructed for the enslaved people, the team is currently excavating a portion of the foundation’s interior to learn more about its construction, layout, and role in the evolving plantation landscape.

Although Washington’s estate is carefully preserved to present its appearance in 1799, archaeologists occasionally uncover evidence of Mount Vernon’s earlier features, providing insight into how the estate evolved throughout Washington’s residence.  For more information, please visit
