pyramids(1)

Built 4,000 years ago, the three great pyramids at Giza, in the Egyptian desert remain the most colossal buildings ever constructed.
The pyramids were built by Egyptians under the orders of the Egyptian leader, whose title was Pharaoh. There was a sequence of Pharaohs culminating around 2615 B.C., with the Pharaoh Cheops who built the biggest thing ever built, the Great Pyramid, also known as Khufu. Cheops built a pyramid 770 feet on one side and 481 feet tall. How ancient builders managed to build these massive structures has never been fully answered but the effort clearly required brains and brawn.
