Commemorating a Century of Honor

The Tomb of the Unknown Soldier, 1921-2021 

For 100 years, the Tomb of the Unknown Soldier has served as the heart of Arlington National Cemetery. As a sacred memorial site and the grave of three unknown American service members, the Tomb connects visitors with the legacy of the United States armed forces throughout the nation’s history. It stands as a people’s memorial that inspires reflection on service, valor, sacrifice and mourning. Since November 11, 1921, the Tomb has provided a final resting place for one of America’s unidentified World War I service members, and Unknowns from later wars were added in 1958 and 1984.

Throughout 2021, Arlington National Cemetery held a series of commemorative events, exhibits and ceremonies that culminated on November 11 in conjunction with the National Veterans Day Observance. We welcome you to explore the following pages that document the centennial commemoration of the Tomb of the Unknown Soldier.
