Arlington House, The Robert E. Lee Memorial is located in Arlington National Cemetery. Arlington House is inextricably linked to one of the most famous Confederate Civil War Generals, Robert E. Lee, but it is also the home of a family whose roots lie with the father of our country, George Washington. Arlington House is where this family lived and lost. It was also home to a large enslaved population that came from Mount Vernon to provide the existence that the family knew. Officially designated as a military cemetery in June of 1864, by U.S. Secretary of War Edwin M. Stanton, more than 300,000 people are buried at Arlington National Cemetery, and more than four million people visit the cemetery every year, many to pay their last respects. During the Civil War, Robert E. Lee left Arlington House and just one month later the plantation was transformed into an army encampment by Union soldiers.
