 At the western end of the burial chamber Perring discovered some fragments of an empty and undercorated black basalt sarcophagus which had been originally placed in a slight depression as well as a canopic chest.The chambers are protected from the pyramid weight by a gabled ceiling made of two large Tura limestone blocks, an architecture common to all pyramids of the 5th and 6th dynasties.The chambers are lined with the same material, while the floor pavement was lost to stone robbers.
