What is the name of the U.S. military cemetery where the World War I Unknown Soldier is buried?

The World War I Unknown Soldier is buried at Arlington National Cemetery.

The Unknown Soldier was interred in the cemetery’s Tomb of the Unknown Soldier on November 11, 1921. The tomb represents American service members whose identities or remains were never established, giving families and the nation a place for collective remembrance.

Arlington National Cemetery is located in Arlington County, Virginia, across the Potomac River from Washington, D.C. It was established during the Civil War on the grounds of Arlington House, the former estate of Robert E. Lee.

The site is central to Memorial Day because it hosts major national ceremonies, wreath-laying events, and military honors. The cemetery also contains the graves of presidents, public figures, and thousands of service members, but the Unknown Soldier’s tomb has a distinct national memorial role.
