How were the Pyramids at Giza built? Show more Show less
Back to question

The Pyramids at Giza are an engineering marvel from Egypt’s Old Kingdom period. The largest, the Great Pyramid, is 455 feet high and was constructed from approximately 2.3 million blocks weighing 2.5 tons each. There are many theories as to how the pyramids were built using primitive technology.

The Internal Spiral Ramp Theory Show more Show less

The Pyramids may have been built in a spiral from the inside-out. The structure of the pyramid itself was used as a ramp. This idea was invented by the Architect Jean-Pierre Houdin and based on the ideas of his engineer father. Recent surveys of the pyramids support this theory.

An internal ramp would work better than an external one

The pyramids may have been built in a spiral from the inside-out. The pyramid itself was used as a ramp. This idea was invented by the architect Jean-Pierre Houdin and based on the ideas of his engineer father. Recent 3D-modelling of the pyramids has given more weight to his theory.

The Argument

The Egyptians probably constructed the pyramids via a system of ramps, which would have allowed them to drag the enormous granite blocks on sleds. Most existing theories about the pyramids include the construction of enormous ramps. Any single external ramp, in order to stay at the right gradient, would have to be more than a mile long. Alternatively, a spiraling ramp would be structurally unstable. By using an internal ramp incorporated into the structure of the pyramid, these problems could be avoided. The internal ramp could easily stay at the required 7-degree gradient, and there would be no problems dealing with the increasing narrowness of the building.[1] If the pyramids were built in a spiral, then the blocks themselves would act as a ramp without the need to construct a complicated external scaffolding. One large external ramp would have been used to make the base of the pyramid, after which the Pyramid would have been built in a spiral. Notches in the internal ramp could be used in combination with cranes to negotiate sharp corners. [2] The inventor of the internal ramp theory, Jean-Pierre Houdin used 3D-modelling software from Dassault Systèmes, which is typically used by architects and engineers, to test his theory. The software appeared to confirm this method would allow ancient humans to successfully build a large pyramid.[3] The internal ramp theory bypasses all the problems with the external ramp models, such as structural soundness, space around the pyramid, and the construction of the pyramid’s corners. The model was successfully tested with 3D-modelling software.

Counter arguments

Many Egyptologists have stated that the theory is excessively complicated and based on conjecture alone. Many different things have to have happened in the internal ramp model for it to have worked. There are many simpler theories which have archaeological evidence, or scientific data to back them up.[4] If the Great Pyramid was built in this way, it would be completely different to the design of every other pyramid that we know of, which all use much simpler techniques. Some people have accused Houdin’s theory of being overly complicated. Other theories, with evidence, are simpler to explain.
