Guédelon Castle

Something interesting (hat tip: David Winter):

Guédelon Castle is a de novo castle construction project located in TreignyFrance. The object of the project is to build a castle using only the techniques and materials used in the Middle Ages. When completed in the 2020s, it should be an authentic recreation of a 13th-century medieval castle.

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 by Philip 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 pond close by. The site is in a rural woodland area and the nearest town is Saint-Sauveur-en-Puisaye, about 5 km to the northeast.
