Woodlawn's mansion house has fallen into disrepair several times, but all of its owners, recognizing its historic significance, have worked to preserve its character. Portions of the property were sold for development or merged into Fort Belvoir over the years. Progressive former U.S. Senator Oscar Underwood, one of the last Southern politicians to fight the Ku Klux Klan before World War II, retired to Woodlawn, where he died in 1929. Only about 160 acres surrounded the mansion house by 1970, and about 126 acres exist today. Since 1965, as discussed below, the Woodlawn Estate property is now also the site of the Pope-Leighey House, a Frank Lloyd Wright designed house. Current status Woodlawn is owned and operated as a museum by the National Trust for Historic Preservation, part of the National Trust Community Investment Corporation. It was the National Trust's first acquisition, achieved in the late 1960s as part of a nationwide campaign that included major donations from philanthropist Paul Mellon. It and the adjacent Pope-Leighey House are open to the public (admission charged) Friday through Monday from April until mid-December. The property name is Woodlawn & Pope-Leighey House. It also hosts special events, particularly weddings and an annual Needlework Show, and hosts museum tours. In 1965, construction on Interstate 66 led to that home built in 1940 by architect Frank Lloyd Wright for Loren Pope to be moved to the grounds of the Woodlawn estate . Four years later, Virginia's historic preservation office nominated Woodlawn, then Woodlawn plantation, for listing on the National Register of Historic Places, and such was approved in 1970. Woodlawn plantation was designated a U.S. National Historic Landmark in 1998, and the boundaries were increased slightly in 2011 by a donation of land from nearby Fort Belvoir which had been part of the Woodlawn plantation. The Quaker meetinghouse once part of the plantation was added to the National Register in 2009. Arcadia Farm leases land at Woodlawn to demonstrate sustainable agriculture by the Arcadia Center for Sustainable Food and Agriculture since 2010. A different plantation with the same name on the Rappahannock River near Port Conway on Virginia's Northern Neck is the centerpiece of the Woodlawn Historic and Archeological District, recognized in 1990.
