<P> Ancient Egyptian temples were aligned with astronomically significant events, such as solstices and equinoxes, requiring precise measurements at the moment of the particular event . Measurements at the most significant temples may have been ceremonially undertaken by the Pharaoh himself . </P> <P> The Giza Necropolis stands on the Giza Plateau, on the outskirts of Cairo, Egypt . This complex of ancient monuments is located some 8 kilometers (5 mi) inland into the desert from the old town of Giza on the Nile, some 20 kilometers (12 mi) southwest of Cairo city center . This Ancient Egyptian necropolis consists of the Pyramid of Khufu (also known as the Great Pyramid and the Pyramid of Cheops), the somewhat smaller Pyramid of Khafre (or Kephren / Chefren), and the relatively modest - sized Pyramid of Menkaure (or Mykerinus / Mycerinus), along with a number of smaller satellite edifices, known as "queens" pyramids, the Great Sphinx as well as a few hundred mastabas, and chapels . </P> <P> The pyramids, which were built in the Fourth Dynasty, testify to the power of the pharaonic religion and state . They were built to serve both as grave sites and also as a way to make their names last forever . The size and simple design show the high skill level of Egyptian design and engineering on a large scale . The Great Pyramid of Giza, which was probably completed c. 2580 BC, is the oldest of the Giza pyramids and the largest pyramid in the world, and is the only surviving monument of the Seven Wonders of the Ancient World . The pyramid of Khafre is believed to have been completed around 2532 BC, at the end of Khafre's reign . Khafre ambitiously placed his pyramid next to his fathers . It is not as tall as his father's pyramid but he was able to give it the impression of appearing taller by building it on a site with a foundation 33 feet (10 m) higher than his father's . Along with building his pyramid, Chefren commissioned the building of the giant Sphinx as guardian over his tomb . The face of a human, possibly a depiction of the pharaoh, on a lion's body was seen as a symbol of divinity among the Greeks fifteen hundred years later . The Great Sphinx is carved out the limestone bedrock and stands about 65 feet (20 m) tall . Menkaure's pyramid dates to circa 2490 BC and stands 213 feet (65 m) high making it the smallest of the Great Pyramids . </P> <P> Popular culture leads people to believe that Pyramids are highly confusing, with many tunnels within the pyramid to create confusion for grave robbers . This is not true . The shafts of pyramids are quite simple, mostly leading directly to the tomb . The immense size of the pyramids attracted robbers to the wealth that lay inside which caused the tombs to be robbed relatively soon after the tomb was sealed in some cases . However, there are sometimes additional tunnels, but these were used for the builders to understand how far they could dig the tomb into the crust of the Earth . Also, it is popular thought that due to grave robbers, future Kings were buried in the Valley of the Kings to help keep them hidden . This is also false, as the Pyramid construction continued for many Dynasties, just on a smaller scale . Finally, the pyramid construction was stopped due to economic factors, not theft . </P>
