Secrets of the Castle - Season 1 (2014)

The team arrives at Guédelon, in the Burgundy region of France, to join the world's biggest archaeological experiment - a 25 year project to build a medieval castle from scratch, using only the tools and materials available in the 13th century.

Ruth, Peter and Tom look at the ingenious features medieval castle-builders came up with to withstand attack from an ever more formidable array of siege engines.

Ruth, Peter and Tom enter the surprisingly colorful world of medieval interior design. The castles that we see today are in fact scarred by centuries of decay. Most of their original roofs, carpentry and interior finishes have long since disappeared, but in their heyday they were lavishly decorated.
