The Building of the Great Pyramids of Giza

Between approximately 2580 and 2510 BCE, three generations of pharaohs — Khufu, Khafre, and Menkaure — built the three Great Pyramids of Giza, along with the Great Sphinx. The Great Pyramid of Khufu, originally standing 146.6 meters (481 feet) tall and composed of approximately 2.3 million limestone blocks averaging 2.5 tons each, was the tallest human-made structure in the world for nearly 4,000 years. Its base is level to within 2.1 centimeters across 230 meters — a precision that astonishes modern engineers. Contrary to popular myth, the pyramids were not built by slaves but by organized teams of skilled and conscripted laborers, housed and fed by the state. The logistics — quarrying, transporting, and precisely placing millions of stone blocks — required sophisticated mathematics, engineering, and administrative organization. The pyramids served as royal tombs, but they were also statements of cosmic order, connecting the pharaoh to the sun god Ra and ensuring the eternal stability of the Egyptian state.
