The original castle in n a rocky spur was supposedly built in 413 by the Visigoths on the side of a mountain, defended by almost inaccessible cliffs. This fortress controlled the Arnette and the Thoré valleys, overlooking the plain where the town of Mazamet now stands.
Pierre-Raymond de Hautpoul is the first known lord of Hautpoul (mentioned in 1084). He rebuilt the castle, constructed the town walls and built the fortified church of Saint-Pierre d'Hautpoul. He accompanied his suzerain Raymond IV of Toulouse on the First Crude to the Holy Land in 1098.
In the 13th century, the lord of Hautpoul and Auxillan was Izarn d'Hautpoul. He reputedly adopted the Cathar faith. The castle and town was besieged by Simon de Montfort in 1212 during the Crusade against the Cathars of the Languedoc. The town was occupied and burned. Its fortifications were destroyed. However the survivors seem to have returned to Catharism as soon as the Crusaders left.
Around 1560, Huguenots (French Protestants) appeared in the region. The castle was besieged again during the wars of Religion between Catholics and Huguenots.
Today, you can still see the long village of Hautpoul winding down the hillside, along with the vestiges of upper and lower castles. At its foot, the river Arnette still winds, and its waters are still perfect for making wool. The old lower town gate has been restored, with its meurtrière. The village is being rejuvenated: picturesque old houses are occupied by craftsmen and their workshops.
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).
