First owned by George Washington''s great grandfather in 1674, this historic estate was composed of five farms by the time Washington became president. His home, built between 1735 and 1787, is considered to have the most magnificent view of any along the Potomac. Today, the estate stretches over 500 acres and includes the mansion, Washington''s Tomb, a Slave Memorial, two museums, 12 outbuildings, magnificent gardens, and a Pioneer Farm site. Exciting tours, programs, and events are offered.
