The badly ruined pyramid of the 8th Dynasty king Ibi is the last pyramid and royal funerary monument to have been built at Saqqara. It was constructed on a low knoll near the causeway of the pyramid of Pepi II in Saqqara-South. Its dimensions are similar to those of the pyramids of Pepi II's queen's: a base length of 31.5 metres and an estimated height of 21 metres.
The core of the pyramid was made of small stones. Only piles of mud and limestone chips remain and it would seem that the builders never got around to set the casing for this monument. Its internal structure is an extremely simplified version of the standard Old Kingdom royal pyramids: it has a descending passage and a burial chamber. A huge granite block in the west of the burial chamber held the sarcophagus. The burial chamber was inscribed with Pyramid Texts.
