The Pyramid of Djoser (or Zoser), or step pyramid 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.
This first Egyptian pyramid consisted of six mastabas (of decreasing size) built atop one another in what were clearly revisions and developments of the original plan. The pyramid originally stood 62 metres (203 ft) tall, with a base of 109 m × 125 m (358 ft × 410 ft) and was clad in polished white limestone. The step pyramid (or proto-pyramid) is considered to be the earliest large-scale cut stone construction, although the pyramids at Caral in South America are contemporary and the nearby enclosure known as Gisr el-mudir would seem to predate the complex.
