The Internal Spiral Ramp Theory

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.

  1. 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.
  2. Recent surveys of the Great Pyramid show an internal ramp
    Multiple archaeological studies of the Great Pyramid using a range of technologies appear to confirm many aspects of Houdin's theory. Cavities found in the walls point to the remains of an internal ramp.
