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.
The pyramid was excavated at the beginning of the 20th century by two different teams who reported conflicting estimates regarding its size and number of subterranean chambers. No artefacts were found over the course of the excavations, and no trace of a burial could be found. For this reason, it is unclear whether the pyramid was used to bury a pharaoh or was abandoned following the premature death of the king.
At the time of its construction the pyramid was surrounded by a necropolis housing large mastabas belonging to the high officials of the 3rd Dynasty state. A mortuary temple was built on the eastern side of the pyramid and a valley temple was possibly located several hundred metres from it. Nowadays, the pyramid is located within the confines of a restricted military area, barring modern excavations of the site.
