The oldest parts of Vansö Church were built in the end of 12th century. It was enlarged to east in the 14th century and again around 1450. The tower cap was demolished in 1765 and rebuilt 1901-1902.
The interior consists of a medieval altarpiece (1400s), crucifix (1270-1300), font (c. 1300) and two reliquaries (1400s). Vaults were decorated with murals in the 1460s.
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.
