In 2007, French architect Jean-Pierre Houdin proposed that the most effective way for the ancient Egyptians to build the Great Pyramid at Giza is the use of an internal ramp that according to the architect still exists inside the ancient Egyptian man made structure.

The first stage of construction, according to Houdin, used a traditional external ramp. The next stage involved building the internal ramp in the shape of a spiral. Once the bulk of the pyramid was finished, the open corners of the ramp were filled in as the pyramid was finished off, but the ramp’s tunnels were left empty. Scientists are now seeking permission from the Egyptian government to do more non-invasive tests that would prove or disprove Houdin’s theory.

The Sound and Light Show at the Great Pyramids takes place on the Giza plateau, around 30 minutes from Cairo. The one-hour show begins with the illumination of the Sphinx, who narrates the history of the pyramids and their builders.

Using laser beams and light projections on the walls of the Mummification Temple, desert sands, pyramid walls and the Sphinx itself, a condensed story of Egypt unfolds. The accompanying soundtrack complements the surroundings and the voice of the Sphinx is suitably dramatic and mysterious!

Archeologist John Romer goes deep inside the Great Pyramid of Giza, where very few have ever been, to reveal its amazing secrets.
