Saint Padarn's Church is one of the largest medieval churches in mid-Wales. Founded in the early sixth century it has gone through many changes, from a Welsh monastic centre, a Benedictine priory, a royal rectory, a church controlled by Chester's Vale Royal Abbey, and since 1538 a parish church under a vicar.
St Padarns is a fine, large thirteenth century church, featuring an aisless nave with transepts and central tower. It was extended around 1475 and was substantially restored in stages from 1867 to 1884 by John Pollard Seddon. Two medieval crosses are preserved within the church.
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.
