Sully was the home of Richard Bland Lee, uncle of Robert E. Lee, and northern Virginia's first representative to congress. He lived here with his wife, Elizabeth Collins Lee, from 1794-1811. During the Lee residency, the farm was supported by enslaved African Americans who were field laborers, domestics and skilled artisans. The home is furnished with Federal period antiques and combines Georgian and Federal architechtural styles. It was restored by Fairfax County Park Authority in 1976. In addition, the site includes the original eighteenth century kitchen-laundry, smokehouse and stone dairy. A representative slave quarter stands southeast of the main house. Representative flower and kitchen gardens complement the site, and the cemetery contains the remains of Mr. and Mrs. Lee.
