What we see of the pyramids today is the stepped core stone which is a coarser limestone than that which was used for the outer casing. On the upper fourth or fifth of Khafre's Pyramid the casing is still preserved. We have evidence that the stripping of the pyramids' fine outer casing began as early as the New Kingdom in ancient Egypt - the era of Tutankhamen, when the pyramids were already 1200 years old, or more! The removal of the casing of the Giza Pyramids, therefore, went on from the 12th century B.C. to the 12th Century A.D.
