History

King Robert II built a castle in 996 in the hills of Montfort. Montfort-l'Amaury was the stronghold of the Montfort family from the start of the 11th century. Amaury I built the ramparts. The Comté de Montfort was related to the Duchy of Brittany following the marriage of Yolande de Dreux-Montfort with Arthur of Brittany in 1294. It returned to the crown of France when Brittany became a part of France under Francis I. The castle was destroyed by the English during the Hundred Years' War.
