Arlington House, the home Confederate General Robert E. Lee shared with his wife Mary Custis who had inherited it as a relative of George Washington, in whose honor it was built.
Lee wrote his resignation letter from the US army here before the Civil War.
His family lost the property during the war, when it was used as a site from which to fortify Washington, DC defenses.
Lee and Custis' son was later paid for the property, which was already being used as a military cemetery.
