With its cloister and Chapter House, Saint-Gaudens Collegiate Church was one of the most important religious buildings in the Comminges area. It was home to a College of Canons Ordinary, a community founded by Bishop Bertrand.
The 11th century Romanesque church, built on the typical Pyrenean plan as a basilica with three naves, stands on the site of an earlier construction. It was extended in the 12th and 13th centuries with the construction of the cloister and Chapter House. The lateral North Door was added in the 16th Century.
References: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).
