The estate, 1,200 acres just west of Leesburg, Virginia off Rt. 7 on Old Waterford Road, was home to two governors: Thomas Swann, a governor of Maryland in the 19th century, and Virginia's reform governor Westmoreland Davis. Morven Park was the last home of Governor Davis, who served his gubernatorial term from 1918 to 1922, and his wife, the former Marguerite Inman of Atlanta, daughter of a wealthy New York cotton broker. Thirteen years after his death in 1942, Mrs. Davis established the Westmoreland Davis Memorial Foundation as a memorial to her husband and the estate was opened to the public in 1967.

Also houses the Museum of Hounds and Hunting and the Winmill Carriage Museum.
