The Pyramid of Menkaure, located on the Giza Plateau in the southwestern outskirts of Cairo, Egypt, is the smallest of the three Pyramids of Giza and is thought to have been built to serve as the tomb of the fourth dynasty Egyptian Pharaoh Menkaure. It was constructed of limestone and granite. The first 16 courses of the exterior were made of granite.
The Great Pyramids were originally bright white When the pyramids were originally finished, they were plated in and outer layer of white “casing stones”. These casing stones were cut with astounding precision to give a smooth slope to the pyramids, unlike how they appear today with the outer stones more or less forming very large “steps”. The original casing stones were made of highly polished Tura limestone, meant to reflect the sun’s rays, and were accurate within 1/100th of an inch.
