Grotto & Well Shaft The internal structure consists of three main chambers (the King's-, Queen's- and Subterranean Chamber), the Grand Gallery and various corridors and shafts.
There are two entrances into the pyramid: the original and a forced passage, which meet at a junction. From there, one passage descends into the Subterranean Chamber, while the other ascends to the Grand Gallery. From the beginning of the gallery three paths can be taken:

a vertical shaft that leads down, past a grotto, to meet the descending passage
a horizontal corridor leading to the Queen's Chamber
and the path up the gallery itself to the King's Chamber that contains the sarcophagus.
Both the King's and Queen's Chamber have a pair of small "air-shafts". Above the King's Chamber are a series of five Relieving Chambers.
