The plantation has been designated as a National Historic Landmark in the United States, cited for the architectural quality of its early Georgian mansion house and the history of its influential family.Since then, Westover has had three subsequent owners, including lawyer John Armistead Selden (a member of the Selden family and the Lee family), whose detailed diaries of daily life at Westover remain in publication as a popular primary source on the economic and cultural history of nineteenth-century Virginian agriculture,[9] and Confederate Army officer Augustus Harrison Drewry.In the early 20th century, Westover was acquired by United States diplomat Richard Teller Crane, II, who restored the mansion and grounds.[3] The house is noteworthy for its symmetry and balance of proportions, secret passages, mid pack gardens, front door, and its Georgian style (which was inspired by the Governor's Palace in Williamsburg, Virginia).The exterior of Westover was used in the pilot episode of "The West Wing" as the home of fictional White House Chief of Staff Leo McGarry.
