Khafre was a son of Khufu and his is the second largest known pyramid in Egypt, only approximately 10 feet shorter than the Great Pyramid. Remnants of its original casing are still apparent at the top of the structure. After the accomplishment of the building of the Great Pyramid, King Khafre had a hard act to follow. Khafre rose to the occasion by building his pyramid on higher ground giving the illusion that his pyramid was taller. He also encased the lowest two courses in granite. The pyramid itself lacks the degree of precision that was present in the Great Pyramid. Its angle is slightly sharper and the four corners are not as well aligned to accurately meet the apex. Therefore it exhibits a slight twist at the top.
