Who is buried in the Unknown Soldier's Tomb in Washington, DC?
On March 4th, 1921, Congress approved a memorial to all those soldiers who lost their lives during World War I.
The sarcophagus contains the remains of a soldier who died in Europe, and was chosen at random by Sgt. Edward F. Younger, a soldier who was highly decorated and received the Distinguished Service Medal. He chose the third of four caskets bearing the remains of four unknown soldiers. The other three were interred in France. The third casket was sent home to America, where it lay in State in the Capitol Rotunda, and was interred at it's present location on November 11, 1921, with President Warren G. Harding presiding.
Other deceased unknown soldiers are also placed in the Plaza, to the west of the Tomb of the Unknown Soldier in flush tombs decorated by white marble.
Those who have died, "...Known only to God..." are perpetually guarded 24/7/365 regardless of weather. These men volunteer for this service. The Tomb is never left unguarded.
