Access to the burial chambers are located inside the adjoining chapel against the north face of the pyramid. The entrance hallway leads to a long descent of eighteen hundred and twenty-three metres. The entrance was once blocked by a plug of granite now lost. The descending passage was probably clogged along its length by large blocks of limestone that thieves have broken up. The debris still littered the passage at the time of discovery. In the descending corridor is a successive horizontal hallway, a vestibule, another hallway, a bedroom with harrows, a final corridor, and a final granite passage which opens into the funerary apartments of the King.
