South pointing air shafts
These small shafts extend out from the rooms in the pyramid to the outer surface of the pyramid. Some experts believe that they were built to provide ventilation for the people working inside the pyramid while it was being built. Other experts believe that these shafts had a religious purpose because they are directed towards certain stars.
This air shaft points towards the constellation of Orion. The ancient Egyptians associated Orion with their god Osiris.
