The Pyramid of Djoser (or Zoser), or step pyramid (kbhw-ntrw in Egyptian) is an archeological remain in the Saqqara necropolis, Egypt, northwest of the city of Memphis. It was built during the 27th century BC for the burial of Pharaoh Djoser by Imhotep, his vizier. It is the central feature of a vast mortuary complex in an enormous courtyard surrounded by ceremonial structures and decoration.
Djoser was the first or second king of the 3rd Dynasty (ca. 2667 to 2648 BC) of the Egyptian Old Kingdom (ca. 2686 to 2125 BC). He is believed to have ruled for 19 years or, if the 19 years were biennial taxation years, 38 years. He reigned long enough to allow the grandiose plan for his pyramid to be realized in his lifetime. Sources
