Did you know the Tomb of the Unknown Soldier is guarded 24 hours a day, 365 days a year by members of the elite 3rd U.S. Infantry, known as The Old Guard? Learn more about this poignant tomb located within Arlington National Cemetery, which contains the remains of unidentified American soldiers from World Wars I and II, as well as the Korean Conflict, and is considered one of the most revered sites in the United States. This poignant exhibit provides a closer look at the history of America's memorial to its fallen heroes, "known but to God." Documents and images from the early 20th century explain how the unidentified servicemen were selected for interment in the tomb, while a display of a full, authentic uniform worn by a member of The Old Guard recreates the presence of the dedicated guard detail. A video presentation of the Changing of the Guard ceremony features the series of precise maneuvers (performed many times each day), which honor the unknown soldiers.
