The stone church of Husby-Ärlinghundra was built in the mid-12th century. The porch and sacristy were added later. The bell tower was erected in 1717 and restored in 1819 to the present appearance.
The sculpture of St. Michael, crucifix and mural paintings date from the Middle Ages. The Baroque-style pulpit was made in 1721.
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.
