Barcaldine Castle is a 17th-century tower house castle built by Sir Duncan Campbell, of Glenorchy, between 1601 and 1609. The castle fell into disrepair in the later 19th century, when Barcaldine House became the principal residence of the family. It was restored between 1897-1911 and now operates as the Barcaldine Castle bed & breakfast hotel.

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.
