The ‘Old Guard’ marks centennial of watching over Tomb of the Unknown Soldier
Arlington National Cemetery is home to the Tomb of the Unknown Soldier, a site that has been in place for over 100 years. Initially, the tomb was not guarded after the soldier's internment in 1921. The burial site was treated as a tourist attraction until concerns over lack of respect led to the posting of an armed military guard.
This change occurred in 1926, with the first sentinel posted on March 25, 1926. Further details about the history of the Tomb of the Unknown Soldier and its guardians, known as the Old Guard, are available from the Department of Defense.
