The Pyramid of Khafre on the Giza Plateau is the second largest in all of Egypt, a truly incredible feat of engineering, but the truth is, it’s very much in the shadow of its big brother, the Great Pyramid.

The interior passages and chambers are far more inferior but they are no less mysterious, and in this video we take a look at the Khafre Burial Chamber, and two small square-shape openings we find in the walls inside. Are these air shafts like we see in the Great Pyramid King's Chamber or are they something else?
