In July 1998, while looking at diagrams of the pyramid of Khufu (Cheops), I noticed something strange in its architecture. I started drawing scale models and, within a few months, I got the conviction that the subterranean southern passage was intended as a shaft similar to those in the upper chambers, although bigger.
The lay out of the chambers and shafts made me think of a geometrical puzzle designed to reveal secret structures. I then developped a theory according to which there would be a secret entrance in the southern part of the pyramid, below ground level. Of course, it would mean that once the pyramid was completed there was no access to the burial chamber of the pharaoh. In that case, one of the following possibilities should be considered:
1) there was a tunnel leading to the secret entrance
2) there was an internal passage until the time of Khufu's burial, that was hidden afterwards
3) the Great Pyramid was completed by Khufu's son, Djedefre
If my theory is right, it would mean that the three known chambers are dummies and that the most mysterious pharaoh of ancient Egypt still rests in a fourth chamber of his Great Pyramid...
Measurements are in Egyptian royal cubits. 1 cubit = 52.36 centimetres (or 20.61 inches)
