The Pyramid of Neferirkare Kakai, known to the Ancient Egyptians as Ba-Neferirkare and variously translated as "Neferirkare is a Ba" or "Neferirkare takes form", is located in the royal necropolis of Abusir.
It is the largest one built during the Fifth Dynasty, equalling roughly the size of the Pyramid of Menkaure.
Workers and artisans who built the pyramid and its surrounding complex lived in pyramid town "Neferirkare-is-the-soul" or "Kakai-is-the-soul", located in Abusir.

The pyramid construction comprised three stages: first built were six steps of rubble, their retaining walls made of locally quarried limestone indicating that the monument was originally planned to be a step pyramid, an unusual design for the time which had not been used since the Third Dynasty, some 120 years earlier.
At this point the pyramid, had it been completed, would have reached 52 m (171 ft).
This plan was then altered by a second construction stage with the addition of filling between the steps meant to transform the monument into a true pyramid.
At a later stage, the workers enlarged the pyramid further, adding a girdle of masonry and smooth casing stones of red granite.
This work was never finished, even after  the works implemented by Nyuserre.

With a square base of 108-metre-long (354 ft) sides, the pyramid would have reached 72 m (236 ft) high had it been completed.
Today it is in ruins owing to extensive stone robbing.
The entrance to the pyramid's substructures was located on its north side.
There, a descending corridor with a gable roof made of limestone beams led into a burial chamber.
No pieces of the sarcophagus of the king were found there.

The pyramid of Neferirkare is surrounded by smaller pyramids and tombs which seem to form an architectural unit, the cemetery of his close family.
This ensemble was meant to be reached from the Nile via a causeway and a valley temple near the river.
At the death of Neferirkare, only the foundations of both had been laid and Nyuserre later diverted the unfinished causeway to his own pyramid.
