Today, Christian is driving us 60 kms south-west to Guedelon.

Guédelon Castle is a castle currently under construction near Treigny, France. The castle is the focus of an experimental archaeology project aimed at recreating a 13th-century castle and its environment using period technique, dress, and material.

In order to fully investigate the technology required in the past, the project is using only period construction techniques, tools, and costumes. Materials, including wood and stone, are all obtained locally. Jacques Moulin, chief architect for the project, designed the castle according to the architectural model developed during the 12th and 13th centuries byPhilip II of France.

Construction started in 1997 under Michel Guyot, owner of Château de Saint-Fargeau, a castle in Saint-Fargeau 13 kilometres away. The site was chosen according to the availability of construction materials: an abandoned stone quarry, in a large forest, with a nearby pond. The site is in a rural woodland area and the nearest town is Saint-Sauveur-en-Puisaye, about 5 kilometres (3.1 mi) to the northeast.

Dressed in woollen smocks, there are quarrymen hewing rocks out of the ground, stonemasons tapping away with their chisels, carpenters hand-sawing trees cut from the local forest by lumberjacks, blacksmiths forging the iron tools, tilers digging clay and ring it in ovens. And transporting all these materials around the site in wooden carts are three carthorses, Paloma, Tyrolienne and Arpège.
