The next time you are at Reagan International, and you have a little time to kill, you can wander out to an area between Garage A and Garage B/C and learn about the Plantation that used to be there.
Abingdon was an 18th-19th century plantation on the site of what is now the airport. Though much of the plantation was destroyed in 1930 (torn down due to neglect), the New Deal Agency, the Civilian Conservation Corps (CCC) helped to preserve and mark portions of the old home. By 1935, Camp NP-6-VA workers had “completed an improved access road, parking area for twenty cars, general landscaping, a concrete pad for a monument at the site, and a new well house, which officials conceived ‘as close as possible to the original design…which was in use when Nellie Custis lived there’” (Eleanor Parke Custis Lewis, known as Nelly, was the granddaughter of Martha Washington and the step-granddaughter of George Washington).
The Abingdon site is still extant and open to the public and has recently been further restored.
