LORTON, Virginia — The side elevation of George Mason's Gunston Hall shows the upper exterior level with three rectangular windows and multiple chimneys rising from the steeply pitched roof. Built between 1755-1759 under the supervision of English architect William Buckland, the brick mansion served as home to George Mason IV, author of the Virginia Declaration of Rights that influenced the U.S. Bill of Rights. The National Historic Landmark property is now owned by the Commonwealth of Virginia and operated as a museum by the National Society of Colonial Dames of America on 550 preserved acres
