Château de Tancarville was built in the 11th century by Raoul, the chamberlain of Dukes of Normandy. In the 12th century the square tower was built with 1.65m thick walls. In 1418 at the time of the conquest of Normandy by Henry V of England, the title of Earl of Tancarville was given to John Grey. After the Hundred Years War the Harcourt family restored the castle. The ballroom was built in 1468. In 1709 the castle was partially rebuilt by the Count of Evreux. After 1789, the castle was plundered and partly burned. In the 1960s , the castle served as a summer camp for children.

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.
