But where did the knowledge and technology for building these monuments come from?

Light floods the interiors of Gothic cathedrals, which have colorful windows instead of solid walls. All told, the windows of Chartres Cathedral in France would cover an area larger than a football pitch.

Another impressive example is St. Stephen's Cathedral in Vienna, Austria, the federal capital's iconic landmark.

This documentary attempts to unravel the mysteries and secrets of Gothic architecture. Ribbed vaults, pointed arches and flying buttresses became integral elements of the Gothic style. The mysticism of light inspired architects to install large windows that illuminated the interior and made visiting cathedrals a truly enlightening experience.

Robust Romanesque construction gives way to the graceful, soaring architectural elements of Gothic style. What secrets lie in the statics of the elongated columns, struts and pillars?

The answers can be found in this documentary, which features experts like Barbara Schock-Werner, former master builder of Cologne Cathedral.

The film also traces the lives of famous Gothic architects. They were universal geniuses, masters of architecture but also of physics, mathematics and chemistry. They kept their knowledge a closely guarded secret to maintain their monopoly and professional status.
