Great Pyramid of Giza
In the Great Pyramid of Giza there are two narrow shafts, in the north and south walls of the King's Chamber. Alexandre M. Badawy suggested that the shafts pointed to Orion's Belt during the period of the construction of the Giza pyramid complex.[1] It is thought that these openings were perhaps "air vents" for mummies or built to point to certain stars at the date of the pyramids construction.[2][3][1]
