2 * Of the the famous Seven Wonders of the Ancient World the Great Pyramid of Khufu (Cheops) at Giza is the only one still standing. Even for modern men it is amazing how this man- made structure lasted so long. * The Giza pyramids must have made an incredible visual impact - at the edge of the desert three abstract geometrical symbols were rising, huge luminous white triangles reflecting the blinding light of the sun! * The pyramids on the Giza plateau are with m (Khufu / Cheops) and m (Khafre / Chefren) respectively the largest, however there are over 30 major pyramids and a myriad of smaller pyramids in Egypt.

7 How the Great Pyramid was built is a question that may never be answered. Herodotus said that it would have taken 30 years and 100,000 slaves to have built it. Another theory is that it was built by peasants who were unable to work the land while the Nile flooded between July and November. They may have been paid with food for their labor. The flooded waters would have also aided in the moving of the casing stones. These stones were brought from Aswan and Tura and the water would have brought the stones right to the pyramid. This pyramid is thought to have been built between BC. It would have taken over 2,300,000 blocks of stone with an average weight of 2.5 tons each. The total weight would have been 6,000,000 tons and a height of 482 feet (140m). It is the largest and the oldest of the Pyramids of Giza.

8 * Not much is known about Cheops (Khufu). The tomb had been robbed long before archeologists came upon it. Any information about him was taken with the objects inside the tomb. He is thought to have been the ruler of a highly structured society and he must have been very wealthy. He was buried alone in this massive tomb. His wives may have been buried nearby in smaller mastabas.Cheops (Khufu)

9 * As you come out of the pyramid you can see the remains of the original enclosure wall which is on the north and east side. It lies about 10m from the base of the pyramid. Little remains of Cheops' Mortuary Temple. What is left is basalt paving and lies near the east side of the wall. You may also see occasional traces of the causeway that led from the valley temple in the village, Nazlat al-Samman, at the foot of the plateau. This causeway collapsed during the last 150 years. Three small pyramids stand to the east of Cheops' pyramid. These are thought to have been for his sister, Merites, who was also his wife, and possibly two other queens.

10 * It's 756 feet long on each side, 450 feet high and is composed of 2,300,000 blocks of stone, each averaging 2 1/2 tons in weight. Despite the makers' limited surveying tools, no side is more than 8 inches different in length than another, and the whole structure is perfectly oriented to the points of the compass. Even in the 19th century, it was the tallest building in the world and, at the age of 4,500 years, it is the only one of the famous "Seven Wonders of the Ancient World" that still stands. Even today it remains the most massive building on Earth. It is the Great Pyramid of Khufu, at Giza, Egypt.Seven Wonders of the Ancient World * Some of the earliest history of the Pyramid comes from a Greek the historian and traveler Herodotus of Halicanassus. He visited Egypt around 450 BC and included a description of the Great Pyramid in a history book he wrote. Herodotus was told by his Egyptian guides that it took twenty years for a force of 100,000 oppressed slaves to build the pyramid (with another 10 years to build a stone causeway that connected it to a temple in the valley below). Stones were lifted into position by the use of immense machines. The purpose of the structure, according to Herodotus's sources, was as a tomb for the Pharaoh Khufu (whom the Greeks referred to as Cheops).

11 The three large pyramids at Giza: From left to right, Menkaure, Khafre, Khufu. The far pyramid is the "Great Pyramid" and the largest structure on the site. The middle one may look larger, but only because it is built on higher ground.

12 * If we were to visit the location of the great pyramid when it was just finished, it would look very different than we see it today. Originally, the pyramid itself was encased in highly polished white limestone with a smooth surface which is now gone. At the very top of the structure would have been a capstone, which is also now missing. Some sources suggest that the capstone might have been sheathed in gold. Between the white limestone and the golden cap the pyramid would have made an impressive sight shining in the bright Egyptian sun.

13 * Around the base of the great pyramid were four smaller pyramids, three of which still stand today. On the east side of the pyramid stood a now missing Funerary temple. Running down the hill into the valley was a stone causeway, which linked the Funerary temple with a temple in the valley. Around the pyramid were six boat shaped pits that may have contained the hulls of vessels that belonged to the pharaoh. Parts of one of these have been found and reconstructed into a 147 foot long boat that today is enclosed next to the pyramid in its own museum. * The other two large pyramids at Giza, the Pyramid of Khafre (Khufu's son) and the Pyramid of Menkaure had not yet been built, so the Khufu's pyramid and its associated structures stood alone, though surrounded by the dwelling places and the graves of many of those that helped construct it.

15 * Working their way down the passage they soon found themselves deep in the natural stone below the pyramid. The corridor stopped descending and went horizontal for about 50 feet, then ended in a blank wall. A pit extended downward from there for about 30 feet, but it was empty. When the workmen examined the fallen block they noticed a large granite plug above it. Cutting through the softer stone around it they found another passageway that extended up into the heart of the pyramid. As they followed this corridor upward, they found several more granite blocks closing off the tunnel. In each case they cut around them by burrowing through the softer limestone of the walls. Finally, they found themselves in a low, horizontal passage that led to a small, square, empty room. This became known as the "Queen's Chamber," though it seems unlikely that it ever served that function. The secret entrance missed by the Caliph's men when searching for treasure.

16 * Egyptian records indicate that the laborers, while being drafted against their will, were actually well cared for by ancient standards. Regulations have been found covering the maximum amount of work allowed per day, the wages received and holidays each worker was entitled to. Also, by scheduling most of the work to be done during annual flood periods, the Pharaoh could get a lot done without impacting the normal Egyptian economy. Workers complete one of the smaller pyramids on the eastern side of the Great Pyramid (Copyright Lee Krystek, 1999).

17 * Some have suggested that the pyramid was never meant as a tomb, but as an astronomical observatory. The Roman author Proclus, in fact, states that before the pyramid was completed it did serve in this function. We can't put too much weight on Proclus words, though, remembering that when he advanced his theory the pyramid was already over 2000 years old. * Richard Proctor, an astronomer, did observe that the descending passage could have been used to observe the transits of certain stars. He also suggested that the grand gallery, when open at the top during construction, could have been used for mapping the sky. * Many strange (and some silly) theories have arisen over the years to explain the pyramid and its passageways. Most archaeologists, however, accept the theory that the great pyramid was just the largest of a tradition of tombs used for the Pharaohs of Egypt.

18 So what happened to Khufu's mummy and treasure? Nobody knows. Extensive explorations have found no other chambers or passageways. Still one must wonder if, perhaps in this one case, the King and his architects outsmarted both the ancient thieves and modern archaeologists and that somewhere in, or below, the last wonder of the ancient world, rests Khufu and his sacred gold.
