Tomb KV17, located in Egypt's Valley of the Kings and also known by the names Belzoni's tomb, the Tomb of Apis, and the Tomb of Psammis, son of Nechois, is the tomb of Pharaoh Seti I of the Nineteenth Dynasty.
In March 1926, soldiers from nearby Fort Myer were first assigned to guard the Tomb of the Unknown Soldier. The guards, present only during daylight hours, discouraged visitors from climbing or stepping on the Tomb. In 1937, the guards became a 24/7 presence, standing watch over the Unknown Soldier at all times.
