Blacksmiths, stonemasons and quarrymen are hard at work in a Burgundy forest building a 13th century-style castle using the most basic tools and materials, replicating the methods used hundreds of years ago to better understand them.
Forgoing all modern technology, workers use hammers to break stones and forge iron, operate wooden wheels to hoist their materials up to where they are needed, and rely on a quarry for stone, clay and sand as they build up a castle from scratch.
