The Buried Pyramid is an unfinished step pyramid at Saqqara built for Sekhemkhet, the second pharaoh of the Third Dynasty, discovered by Zakaria Goneim in 1951. Planned as a 120 m square structure rising to 70 m in seven steps within a 500 x 200 m enclosure, it would have surpassed Djoser's pyramid in scale, but the king's untimely death halted construction at an early stage. A unique sealed alabaster sarcophagus with a sliding door was found in the burial chamber, but was mysteriously empty despite appearing undisturbed. Imhotep's name was discovered in a graffito on the enclosure wall, suggesting he oversaw both this and Djoser's complex.
