The exact function of this structure is unclear. The corridor leads to the royal burial chamber, where now stands the sarcophagus of red granite, with no cover. It has no decorations, no inscriptions. Judging by the size, he was placed in a cell in the process of building the pyramids. Its length is 2.24 m, width 0.96 m. from the person for whom it was intended, not a trace remains. A very effective ventilation system, linking the northern and southern sides, allows freshen the air inside the room, which is very useful during the influx of tourists. Above the ceiling, composed of nine granite blocks, weighing 400 tons, there are five intermediate rooms, designed to facilitate a phenomenal load, which should make burial chamber. We must not forget that the total mass of the pyramid is about 7 million tons! At the very top of these chambers, archaeologists Wiese and Perring in 1837 found the only thing that relates to the attributes of a pyramid: the red ink written cartouche of Pharaoh Khufu. This is the only inscription which is preserved throughout the pyramid. To the east of the pyramid of Cheops are two holes in the shape of boats, where there was a boat of Pharaoh, and three additional pyramids: the south has been the burial place of Queen Henutsen, daughter of Sneferu and Khufu's blood sister, is buried in the middle Meritetis, and the third was built in honor of the mother of Pharaoh Hetep-herses . Due to the fact that this grabnitsa been looted after the death of the queen, Cheops ordered built for his mother's secret tomb, carved in the rock just to the north. Pharaoh was so well-hidden tomb of the queen, that she was discovered only in 1925 by the American archaeologist George Reisner. It was found funerary items now on display in the Cairo Museum.
