Timewatch - 2008-2009 - Pyramid - The Last Secret

For centuries archaeologists have been trying to work out how the ancient Egyptians raised huge stone blocks to the top of the Great Pyramid. This documentary presents a radical theory by French architect Jean-Pierre Houdin. He believes that an internal ramp was used, which is still inside the Pyramid waiting to be discovered. If he is right, it is the greatest discovery since Tutankhamun.
