A pencil sketch of Pyramids of Egypt. One of the oldest wonder of the ancient worlds is that still survives the group of Pyramids in Giza, Egypt. On the west bank of the Nile near Cairo. The largest of them , the Great Pyramid of Khufu, was built by the pharaoh Khufu around the year 2560 B.C, to serve as his tomb. It is thought to have taken 100,000 laborers about twenty years to build, using an estimated 23 million blocks each weighing more that two tons.
This Pyramids base was 756 feet on each side, and when completed the pyramid was about 480 feet high. For more than forty three centuries it was the tallest structure on earth, not to be surpassed till the nineteenth century A.D. On the north face is an entrance form which corridors, galleries and escape shafts lead to the King's burial chamber or were used for other functions.
