"Of all Egypt's pyramids, the is by far the most mysterious. It's so imposing, so perfect you can see why many insist it couldn't possibly be the work of mere mortals. It has to be a creation of the gods, either that, or aliens. At last it seems this ancient riddle has been solved. There's one man who reckons he's figured it all out. He's willing to share his amazing discovery with us. To take us to the very heart of the mystery, deep inside the Great Pyramid, where very few have ever bee"

At the age of the first ancient wonders of the world began with the pyramids of Sneferu. The two pyramids build at Dahshur one called the Bent Pyramid because its upper part has a shallower angle of inclination of the lower part. Bent pyramid diagram Seneferu's Bent pyramid at Dahshur was originally planned as a true pyramid, but its geometry was altered at a point just above half its height.  When Khufu became pharaoh one of his first acts was to curtail the growing power of the priesthood. He "shut up all the temples and forbade sacrifices". As a priest’s living came from performing these rituals it is not surprising that Khufu was unpopular with the religious orders.

I you are looking to Giza Pyramid diagram, some people believe that his pyramid at Giza was built by slaves but this is not true. One hundred thousand(100,000) people worked on it for three months of each year. He provided good food and clothing for his workers and was kindly remembered in folk tales for many centuries. This was the time of the Nile's annual flood which made it impossible to farm the land and most of the population was unemployed.  There are three pyramids at Giza, each of which once had an adjoining mortuary temple. Attached to this temple would have been a covered causeway descending down to a valley temple, near the Nile. The 'great' pyramid itself is truly an astonishing work of engineering skill - for over four thousands years, until the modern era, it was the tallest building in the world. Giza PyramidThe sides are oriented to the four cardinal points of the compass and the length of each side at the base is 755 feet (230.4 m). They rise at an angle of 51 52' to a height , originally, of 481 feet (147 m) but nowadays 451 feet (138 m). It was constructed using around 2,300,000 limestone blocks, weighing, on average, 2.5 tons each. Although some weigh as much as 16 tons. Until recently, relatively speaking, it was cased in smooth limestone but this was plundered to build Cairo. Is it conceivable that by bringing together so many people and giving them a common goal, that of making a mountain, a national identity is forged in their hearts. From Upper and Lower Egypt communities would have got to know each other and a common bond would have been manifest in the object of the pyramid. If this is true it is unique because all other forms of nationalism have grown out of war. For example England and France in the Hundred years war and the USA through the revolutionary, civil and Indian wars. The Great Pyramid of Giza is one of the seven wonders of the world.
