Sekhemkhet

Sekhemkhet began construction of a step pyramid at Saqqara, now known as the Buried Pyramid. The pyramid was planned to be larger than Djoser's step pyramid but was left unfinished, with only the base and lower courses completed. The site includes a surrounding enclosure wall and subsidiary tombs.

The burial chamber of Sekhemkhet's pyramid was found empty, with an alabaster sarcophagus still sealed but containing no remains. This suggests the pharaoh may not have been buried there, or the tomb was robbed in antiquity. The discovery provided insights into early pyramid building techniques.
