Castillejo de Robledo castle and its lands were property of the Order of Malta until it was suppressed by Pope Clement V in 1311. After that the estate passed to the Knights Hospitaller and then to the residents of the town. In the town there was an old Moorish fortification where the current castle was built in the 12th century. The remains of the original wall are visible and are characterized by a greater thickness than the walls erected later.
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.
