هرم زوسر
The Pyramid of Djoser (or Djeser and Zoser), or Step Pyramid ("kbhw-ntrw" in Egyptian), is an archaeological site in the Saqqara necropolis, Egypt, northwest of the city of Memphis. The 6-tier, 4-sided structure is the earliest colossal stone building in Egypt. 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.
