White grave markers -- white robes
The Arlington House was a mansion built as a living memorial to George Washington by the first president's adopted grandson. The estate was built on a 1,100-acre tract of land across the Potomac River from Washington DC. Decades later a distant cousin, Robert E. Lee, became the resident of the home. Between 1841 and 1857, Lee was away from Arlington House for several extended periods while serving in the Mexican War and then as superintendent of the U.S. Military Academy at West Point, his alma mater. In 1857 Lee returned to Arlington to join his family and to serve as executor of the estate.
