Château de Châteaudun dominates the landscape of Châteaudun in Centre-Val de Loire, perched on a rocky spur overlooking the town and the Loir river. Originating with a 12th-century dungeon built by Count Thibaut V of Blois, the castle witnessed a remarkable architectural evolution spanning five centuries. The 31-metre cylindrical keep with 4-metre-thick walls marks the medieval core, while 15th-century additions by Jean de Dunois—companion of Joan of Arc—introduced Gothic residential wings and a chapel. The 16th-century north wing in Louis XII style blends flamboyant Gothic and early Renaissance design. Classified as a historical monument in 1918, the castle preserves remarkable 16th- and 17th-century tapestries and a chapel featuring 15th-century statuary and a Last Judgment fresco from 1467.
