A view of the Tomb of the Unknown Soldier captured from Roosevelt Drive in Arlington National Cemetery. “Americans have long sought ways to honor those who made the ultimate sacrifice to their country. Today in Arlington, Virginia, the public is welcome to do so daily by bearing witness to the Changing of the Guard. The tradition honors the Tomb of the Unknown Soldier, a tribute to unidentified members of the military lost in service. The Tomb, first erected in 1921, is located in Arlington National Cemetery. It holds the remains of servicemen from World War I, World War II, and the Korean War. Throughout the day, a Soldier replaces a comrade in a symbolic ceremony.” – National Museum of the US Army
