Guédelon is the world’s biggest experimental archaeological site – and some would say the most ambitious too. Since first breaking the ground in 1997 the workforce have used the tools and techniques of the 13th century to unravel the mysteries of medieval construction.

And since they are resurrecting the crafts and methods of an age before mechanization, it’s all been done by hand. Which, in turn, means that everything is dependent on the skills of the workforce – a small army of stonemasons, blacksmiths, carpenters, wood-cutters, tilers, rope-makers and dyers who hand-craft every component on site.
