Great Pyramid of Khufu

The northernmost and largest Great Pyramid of Khufu (Cheops) is considered the greatest single building ever built by man. The pyramid no longer reaches its original height (481 2/5 feet) because its outer casings of smooth white limestone have been removed. Almost 2,300,000 blocks of stone (averaging 2.5 tons each) were used to construct this building.
