(CNN) The Tomb of the Unknown Soldier is at Arlington National Cemetery. Congress approved the burial of an unidentified World War I soldier in the plaza of the then-new Memorial Amphitheater in 1921. There are also six wreaths, three sculpted on each side, that represent the six major campaigns of World War I. Edward F. Younger chose the Unknown Soldier of World War I, who now lies in the tomb. In 1956, President Dwight D. Eisenhower signed a bill to select and pay tribute to the unknowns of World War II and Korea.
