According to ''National Geographic'' it took an estimated 20,000 to 30,000 workers to build the Pyramids at Giza over a period of 80 years from about 2570 to 2490 B.C. and slaves were not used.
The Great Pyramid of Giza was built around 2700 - 2500 BC. The Great Pyramid of Giza is in city of Giza, Egypt on the west bank of the Nile River, near Cairo. Out of all the Seven Wonders of the World, the Egyptian Pyramids are the oldest and only surviving wonders. No wonder they're wonders. (Okay, okay, that was a cheesy joke.) All three of the Great Pyramids are amazing but only the Great Pyramid of Khufu is considered a wonder. King Khufu of the Fourth Dynasty built the monument so he had a tomb to be buried in. It is said that the pyramid took over 20 years to construct.
