Sarrance Monastery belonged to the Betharram Fathers who had replaced the Premonstratensians who left after the French Revolution. The Premonstratensian order founded their monastery in this place in 1345, the site of a Marian pilgrimage dating from the 12th century. They maintained religious services in this place, served the parish and welcomed pilgrims and travellers on the Roman road to Santiago de Compostela.
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.
