Guédelon Castle (French: Château de Guédelon [ʃɑto d(ə) ɡedlɔ̃]) 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 techniques, dress, and materials. 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 (8.1 mi) 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.
