Photographer: Ahmed A. Saada, MD, FICS, Alexandria, Egypt. This picture was taken on the Giza Plateau, Egypt in January 2008, and shows the 3 most famous pyramids of Giza. The Great Pyramid is the oldest and the only remaining member of the Seven Wonders of the Ancient World. It was built in 2550 bc as a tomb for Pharoah Khufu (also known as Cheops) who was the second king in the fourth dynasty. This pyramid incorporates about 2.3 million stone blocks, weighing an average of 2.5 to 15 tons each. The total height is about 147 m (481 ft). The middle pyramid is that of Khafrae and the small one is the pyramid of Menkaure.
