Step Pyramid of Djoser in the center of a huge rectangular area measuring 544 by 277 meters, surrounded by a partially destroyed wall of limestone. Part of the wall has been restored from numerous fragments found in the sand. The reconstruction shows that it was originally a height of about 10 m. Imhotep, architect and minister of Pharaoh Djoser - the first ruler of Dynasty III, built later in the rank of God, built the "mother of all pyramid schemes," and thus created the first monumental stone building in the world. At the base of the pyramid of Zoser is an irregular quadrilateral with sides 110 and 120 m, the height of 60 m. Originally it was a width of 63 m mastaba and a height of 8 m. Under the mastaba is a well depth of 28 m at the bottom of which was arranged a burial chamber, connected to the system tunnels with rooms for burial utensils (here, in particular, has been found many stone vessels and pots) and other passages and rooms, decorated with blue faience and intended to stay Ka (body) of the pharaoh. To the northeast is serdabe-small room inside the tomb, where there was sculpture of the deceased. Now it is the pride of the exposure of the Cairo museum. In Saqqara, is it an exact copy.
