Pyramids of Giza
Of the Seven Wonders of the World, the famous pyramids located in Giza, near the city of Cairo, Egypt, are the only ones remaining nearly intact.

About 2,550 B.C., King Khufu, the second pharaoh of the fourth dynasty, commissioned the building of his tomb at Giza. Some Egyptologists believe it took 10 years just to build the ramp that leads from the Nile valley floor to the pyramid, and 20 years to construct the pyramid itself.

Khufu's son, Khafre, who was next in the royal line, commissioned complex which includes the sphinx, Menkaure, who is believed to be Khafre's son, built the third and smallest of the three pyramids at Giza.

Giza, however, is more than just three pyramids and the Sphinx. Each pyramid has a mortuary temple and a valley temple linked by long causeways that were roofed and walled. Alongside Khufu and Khafre's pyramids were large boat - shaped pits and buried boats that were presumably meant to aid the pharaoh's journey to the afterlife. As yet, no vessels have been found beside Menkaure's tomb.

Khufu, Egyptian king (reigned 2551-2528 bc) was the second king of the 4th Dynasty, also known as the Memphite dynasty.
