Giza Necropolis (also called the Giza pyramid complex) is on the Giza Plateau near the city of Cairo, Egypt. It is about 8 kilometres (5 mi) inland into the desert from the ancient town of Giza on the Nile, and about 25 kilometres (12.5 mi) southwest of Cairo city centre. The Great Pyramid is the only remaining monument of the Seven Wonders of the World.

Construction of the Great Pyramid
There have been many theories to explain how the pyramids were built. These theories include:
- the use of external or outside ramps
- the use of cranes
- the use of an internal or inside ramp. This idea was developed by Jean-Pierre Houdin, a French architect. He has also made detailed computer models of the Great Pyramid. Houdin says that the ramp spirals upward. There is evidence in the notched corners of the pyramid. Not only was the spiraling internal ramp used, but an external ramp was probably used to move the bigger blocks. These are in the lower half of the pyramid and probably used simple cranes to lift them.
- the rack and pinion theory developed by Paul Hai. Hai published his theory on 27 August 2006 as part of an Australian university assignment. Herodotus of Halicarnassus asked the ancient Egyptians themselves how the Giza Pyramids had been built. This is a rampless theory and fully explains the workings of the wooden machines described by Herodotus. This uses a three-wheel step trolley, climbing steps so that ramps are not needed. In Part One of his book, the full details are carefully explained with many pictures and photographs of a working model.
