The Layer Pyramid (known locally in Arabic as el haram el midawwar, Arabic: الهرم المدور‎, meaning 'rubble-hill pyramid') is a ruined step pyramid dating to the 3rd Dynasty of Egypt (2686 BC to 2613 BC) and located in the necropolis of Zawyet El Aryan. Its ownership is uncertain and may be attributable to pharaoh Khaba. The pyramid architecture, however, is very similar to that of the Buried Pyramid of king Sekhemkhet and for this reason is firmly datable to the 3rd Dynasty.
