In 72 BCE the Roman General Pompey, while on the way back to Rome after a military campaign in Spain, founded a Roman colony in Saint-Bertrand-de-Comminges. The goal was to defend the passage to the Aran Valley and the Iberian peninsula. The colony was named Lugdunum Convenarum and had reached around 30,000 people at its highest point. It belonged to the Roman province of Novempopulana and had a growing Christian community, which by the late fourth century got its own Diocese of Comminges, which was suffragan of the Metropolitan Archdiocese of Eauze.
It is believed to have been the place of exile from 39 AD of Herod Antipas, with his wife Herodias, under Emperor Caligula's orders. In 405 the Vandals sacked the city and forced the peasantry to move to the citadel.
In an open field just outside the village centre, this small archaeological site has a few ruins from the town's Roman days. You'll have to use your imagination to picture the theatre, market, temple and other public buildings from the fragments of low-rising stone foundations.
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.
