The Great Pyramid of Giza, built for Pharaoh Khufu (Cheops) during Egypt's Fourth Dynasty around 2560–2540 BCE, remains one of humanity's most astonishing architectural achievements. Standing on the Giza Plateau near modern Cairo, this monument represents the pinnacle of Old Kingdom pyramid construction.
Khufu's pyramid was the tallest human-made structure in the world for over 3,800 years — until Lincoln Cathedral's spire surpassed it in 1311 CE. The precision of its construction is remarkable: the base is level to within 2.1 centimeters, and the sides align to true north with an error of only 3/60th of a degree.
How ancient Egyptians quarried, transported, and positioned millions of multi-ton blocks with Bronze Age tools remains a subject of ongoing research. Leading theories involve ramp systems (straight, zigzag, or spiral), levering techniques, and a highly organized workforce of skilled laborers — not slaves, as once believed.
The Great Pyramid wasn't built in isolation. It anchors a complex including two major temples, smaller queens' pyramids, boat pits, and the famous Sphinx — together forming a sacred landscape designed to ensure the pharaoh's eternal journey.
