As with most other pyramids, the north face
is the side that has the entrance to the passageway and chambers of the
pyramid. As with the other Abu Sir pyramids, the entrance to Niuserre's
pyramid is blocked with rubble and debris and cannot be entered. The interior
consists of a descending passageway which levels out and was blocked by
portcullis blocks. This led to another descending passageway which lead
to an antechamber, again with a gable roof. The burial chamber was to the
west of the antechamber and also contained a gabled roof made of three layers
of limestone blocks.
