1 The curvature designed into the faces of the pyramid exactly matches the radius of the earth. 2  Khufuâs pyramid, known as the great pyramid of Giza, is the oldest and largest, rising at 481 feet (146 meters). 3  Archaeologists say it was the tallest structure in the world for about 3, 800 years.
But the process of building pyramids, while complicated, was not as colossal an undertaking as many of us believe, Redford says. Estimates suggest that between 20,000 and 30,000 laborers were needed to build the Great Pyramid at Giza in less than 23 years. By comparison, Notre Dame Cathedral in Paris took almost two hundred years to complete.
