The inner structure of Khafre's pyramid is quite simple. There are two main entrances. The lower descends slightly before ascending somewhat. At this point it meets the passage from the upper entrance. A long corridor (upper photo) leads straight to the burial chamber (lower photo). In the burial chamber there is little to see except a sarcophagus made from black granite. Along the lower passage there is a subsidiary chamber. Nobody knows which purpose this served. It could have been the queen's chamber. Although it appears as if the corridor and burial chamber are perfectly placed according to the pyramid's exterior, this is not the case. The corridor lies as much as 12 metres to the east compared to the north-south axis. Khafre's pyramid was since old times considered without any opening. But it was a rather fascinating figure of Egyptian research, Belzoni, who blasted open the portal in 1818. Belzoni had a background as a strongman in a circus.
