nass_news_2011_oct_mount_vernonGeorge Washington's Sundial is in the Spotlight: Sometime during 1765-1781 Washington placed a 12 inch brass horizontal sundial at the heart of his Mount Vernon plantation. The sundial sits atop a white painted octagon wood pedestal in the center of the front lawn of his mansion.  It stands as a visual reminder of the importance of time to all who passed it.  A replica of the original dial now reminds tourists of the time, but the original is in the museum.  Go to and read more about Mount Vernon and visit NASS_Registry_Dial167 where you can find details of Washington’s dial.
