The Pyramids of Egypt

 

The only surviving wonder of the ancient world, the Pyramids of Egypt (Giza), were the phenomenal achievement of Egyptian construction and engineering. Built between 2600 and 2500 B.C., the three pyramids at Giza encompass more than 5 million limestone blocks which were painstakingly transported via timber sleds and by being rolled over the top of logs.

As cranes were as yet unheard of, each block had to be dragged via ramps up to its designated place. According to Herodot, the largest of the three pyramids, known as the Great Pyramid, (about 146 meters high) took 20 years to complete and served as the tomb for the Egyptian Pharoah Khufu. The pyramids represented the link between heaven and earth and were a signal to Horus, God of the World.
