Building the Great Cathedrals

Directed by Christine Le Goff and Gary Glassman

With Féodor Atkine, Joan R. Branham, Frank Helmholz, Stefaan Van Liefferinge and Thibaut Desjardins

These skyscrapers of stone dominated skylines for nearly a thousand years. Now, a team of scholars and builders investigates how they we went up, and why some of the tallest fell down. Embedded in stone and stained glass, they uncover a hidden mathematical code — ripped from pages of the Bible — that was used as a blueprint to build the great Gothic Cathedrals.
