Star shafts

Star shafts are narrow ducts leading out of ancient structures such as the Egyptian pyramids and Baalbek. The shafts start inside the Kings Chamber of the Great Pyramid of Giza, and exit at the same height. Alexandre M. Badawy suggested that the shafts pointed to Orion's Belt during the period of the construction of the Giza complex. 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.
