Tomb of the Unknown Soldier (Arlington), Washington D.C.

The Tomb of the Unknown Soldier, also known as the Tomb of the Unknowns, serves as a memorial to American military personnel who bravely fought and lost their lives in World Wars I and II, the Korean War, and the Vietnam War. These individuals remain unidentified.

Constructed in 1921, this tomb is a prominent monument situated on a hill overlooking Washington, D.C. It comprises a large white sarcophagus containing the remains of these unidentified soldiers. Notably, the "Unknown" from World War I was honored with the Medal of Honor, the Victoria Cross, and various other prestigious foreign service awards. Similarly, the American "Unknowns" interred here were posthumously awarded the Medal of Honor, presented by U.S. Presidents who attended their funerals.

The tomb is under constant vigilance, with Tomb Guard sentinels from the distinguished 3rd U.S. Infantry Regiment standing watch 24 hours a day, 365 days a year. The Changing of the Guard ceremony is a solemn and intricate ritual. During this ceremony, a sentinel seamlessly takes over guard duty from their predecessor, involving a special march and salute. This ceremony occurs hourly from October to March and every half-hour from April to September.
