The Great Pyramid of Giza contains three separate chambers: one serves as the burial location for King Khufu, while the other two contain a statue of the king and a sacred sarcophagus. According to National Geographic, historians initially believed one of the two chambers in the Great Pyramid, still referred to as the queen's chamber, served as a burial site for one of his wives. However, further explorations reveal all chambers memorialize King Khufu.
In addition to three distinct chambers, the interior of the Great Pyramid appears as a labyrinth. Narrow passageways, shafts and corridors connect the three rooms, which exist on multiple levels. The lowest level of the Great Pyramid contains the unnamed chamber. This chamber, never intended for viewing, forms from granite and resides deep in bedrock. It contains little besides a small sarcophagus. An ascending chamber connects that chamber with the Grand Gallery on the main level. This tall room serves as a main entrance; an ancient security system of sliding granite blocks prevented theft and discouraged criminal activity.
The queen's chamber resides on the main floor too, situated right behind the Grand Gallery. The king's chamber exists on the top level of the Great Pyramid. An ascending passageway connects the queen's chamber with the king's chamber. His chamber contains a large sarcophagus and a royal coffin.
