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.
Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
