Quoile Castle is a 16th-century tower house, which was inhabited into the 18th century. The south corner of the building has fallen down and shows a cross-section of the castle. In the north east wall the doorway has been rebuilt and gives access to a straight mural stairway. This is protected by murder-holes at the bottom and at the top. The inner doorway at the ground floor opens into a chamber with a stone vault and many small gun-loops. Beyond this is a second similar chamber. The first floor has two rooms and one of them has a fireplace. The second floor is reached by another straight stairway within the north west wall. There is another fireplace at this level.
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.
