Unlocking the Great Pyramid

When ancient architects completed construction on the Great Pyramid at
Giza, they left behind the greatest riddle of the engineering world
how did builders lift limestone blocks weighing an average of two and
a half tons, 480 feet up onto the top of the pyramid? For centuries,
adventurers and Egyptologists have crawled through every passageway
and chamber of the Great Pyramid, measuring and collecting data in an
attempt to determine how it was built. For the first time, a
revolutionary theory argues that the answer may be inside the pyramid.
Architect Jean-Pierre Houdin has devoted his life to solving this
mystery by creating incredibly accurate blueprints of the Great
Pyramid, using cutting-edge 3-D software. Unlocking the Great Pyramid
follows Houdin and renowned Egyptologist Bob Brier in Giza as they put
Houdins theory to the test.
