Arlington House once belonged to Confederate General Robert E. Lee, whose wife, Mary Custis, a great-granddaughter of George Washington, inherited the home. During the Civil War, Union troops made the house their headquarters. The home is furnished as it was when the Lees raised their seven children here. Park rangers dressed in period costume help dramatize the era. Enjoy a stunning view of Washington from the front of the hillside mansion. As the mansion is located within Arlington National Cemetery, visitors must either walk from the Visitor Center or join the Tourmobile Sightseeing tour of the cemetery.
