Arlington House, The Robert E. Lee Memorial, is a Greek revival style mansion located in Arlington, Virginia, on bluffs overlooking the Potomac River, directly across from the National Mall in Washington, D.C.. During the American Civil War, the grounds of the mansion were selected as the site of Arlington National Cemetery, in part to ensure that Confederate General Robert E. Lee would never again be able to return to his home. Yet the United States has since designated the mansion as a national memorial to its former opponent, a mark of widespread respect for Lee in both the North and South. This magnet commemorates this historic site.
