The pyramid of Djoser (or Djeser and Zoser), sometimes called the Step Pyramid of Djoser, is an archaeological site in the Saqqara necropolis, Egypt, northwest of the ruins of Memphis. The 6-tier, 4-sided structure is the earliest colossal stone building in Egypt. [4] It was built in the 27th century BC during the Third Dynasty for the burial of Pharaoh Djoser. The pyramid is the central feature of a vast mortuary complex in an enormous courtyard surrounded by ceremonial structures and decoration. Its architect was Imhotep, chancellor of the pharaoh and high priest of the god Ra.
