Château d'Arques-la-Bataille was originally a motte-and-bailey castle built to the steep hill around 1050. The castle was reconstruted in the 12th century. The long curtain wall and moat surrounded the Norman style donjon, a keep. The castle saw several battles and besieges during the centuries; the rebellion in 1052, Hundred Years' War and the most well-known in 1589 as part of the Wars of Religion. In 1688 the château was abandoned and later partially demolished and sold as the private property. Today the magnificent Château d'Arques-la-Bataille lies in ruins.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
