The mortuary complex of Pepi I is situated in the southern archaeological complex of Saqqara, Egypt. It was excavated in the 1960s by the French Archaeological Mission of Saqqara (MafS) which, all around the main pharaoh's pyramid, discovered about ten new pyramids for the queens and family of this pharaoh. Several have Pyramid Texts (Akhenespepy II, Behenou, Reherichefnakht)
The pyramid was 150 cubits per side at the base and 100 cubits high (78.75m sq x 52.5m high) The core was made of small, locally quarried stone and debris fill which was clad in layer of white limestone. The limestone has since been taken, exposing the core which has slumped. The inner chambers followed the same plan as previous 5th Dynasty pyramids, they were formed in a 'pit and ramp' and the pyramid was built above.
