The Buried Pyramid (also called the Pyramid of Sekhemkhet) is an unfinished step pyramid constructed ca. 2645 BC for Sekhemkhet Djoserty, second pharaoh of the third dynasty and successor of Djoser. It is located a few hundred meters southwest of the Step Pyramid Of Djoser at Saqqara.
The pyramid, today only 8 metres (26 ft) high, was discovered in 1952 by Egyptian egyptologist Zakaria Goneim. The burial chamber was found intact and the sarcophagus sealed, yet empty. It remains that the pyramid of Sekhemkhet is the only known royal pyramid whose burial chamber was found unviolated. Nowadays, the aboveground part of the ruins are open to the public, but not its substructures.
