Great Pyramid built inside out
‘A French architect says he has cracked the 4500-year-old mystery surrounding Egypt’s Great Pyramid – 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 3-D technology had shown the main ramp which was used to haul the massive stones to the apex was contained 10 to 15 metres beneath the outer skin, tracing a pyramid within a pyramid.’
