How the Great Pyramid Was Really Built

The Great Pyramid of Giza stacked 2.3 million limestone blocks, each averaging 2.5 tons, in roughly 20 years. It stood 481 feet tall and kept the world height record for 3,800 years, yet its base, covering 13 acres, sits aligned to true north within three sixtieths of a degree. No lasers, no cranes, just surveying, ramps, and relentless organization.
