The construction time for a pyramid varied depending on its size and complexity, but the Great Pyramid of Giza, for example, is believed to have taken about 20 years to complete. Built during the Fourth Dynasty of the Old Kingdom of Egypt, it required a massive workforce and advanced engineering techniques. Other pyramids may have taken less or more time, but the 20-year estimate is commonly cited for large royal pyramids.
