The grey-stone church of Ärentuna was built around the year 1300. It was probably inaugurated in 1302, when archbishop Nils Allesson visited in Ärentuna parish. The original barrel vault of wood was replaced by brick-made cross-vaults before the church's reopening in 1435. The well-preserved mural paintings, made by unknown “Ärentuna master” date also from 1440-1450s. The bell-tower was reconstructed in 1772.
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.
