Photo: Great Pyramid Mystery to Be Solved by Hidden Room?



A controversial theory says ancient Egypt's Great Pyramid was built using a winding, inclined, interior tunnel through which huge blocks were pushed. The interior ramp would have required open corners (illustration at top) at which the blocks would have enough room to be rotated—probably by workers using wooden cranes—the theory says.

The theory may be supported by new ideas about a hidden room high in the pyramid's outer wall. Egyptologist Bob Brier, shown entering the space, says it is in fact one of those open corners, long since walled in.
