Used as a burial chamber for nearly 500 years from the 16th to 11th century BC, Discovered by Howards Carter in an excavation expedition in 1922, one of the most important tombs found in the Valley of the Kings is the tomb of Pharaoh Tutankhamun and all of his treasures. The Valley of the Kings is located on the west bank of the Nile River near Luxor. It is the most famous site for having unique collections of tombs and breathtaking ancient ruins.
