The Great Pyramid of Giza, also known as the Pyramid of Khufu (or
Cheops), in Egypt is the only one of the Seven Wonders of the Ancient
World still standing. It is also the oldest. The Great Pyramid is the royal
tomb of the Egyptian Pharaoh Khufu who lived about 2560 B.C. It originally
stood more than 480 feet and is estimated to be made up of 2.3 million
blocks, some weighing up to 9 tons a piece!
