Great Pyramid was built inside out, Frenchman says By Tim Hepher Fri Mar 30, 12:12 PM ET
A French architect said on Friday he had cracked a 4,500-year-old mystery surrounding Egypt's Great Pyramid, saying it was built from the inside out.
Previous theories have suggested Pharaoh Khufu's tomb, the last surviving example of the seven great wonders of antiquity, was built using either a vast frontal ramp or a ramp in a corkscrew shape around the exterior to haul up the stonework.
But flouting previous wisdom, Jean-Pierre Houdin said advanced 3D technology had shown the main ramp which was used to haul the massive stones to the apex was contained 10-15 meters beneath the outer skin, tracing a pyramid within a pyramid.
