Originally devoted to Saint-Sernin, first bishop of Toulouse, the Saint-Hilaire abbey later took the name of Saint-Hilaire who was Bishop of Carcassonne during the 6th century, because relics of his mortal remains were apparently sheltered there.
It was during the medieval period that this locality grew in importance, the village spread around the abbey whose abbots were also the feudal lords.
Until the beginning of the 13th century, the abbey benefited from the protection of the Counts of Carcassonne. During the Crusade against the Cathars, however, the monks were accused of heresy and lost their autonomy and most of their property. The monastery itself was devastated by the Catholic Crusaders. In 1246, Saint-Louis, the French King, ordered the Seneschal of Carcassone to give back to the Abbot of Saint-Hilaire the lands which had been confiscated from Cathars.
By the 14th century, the abbey was in financial difficulty. Insecurity caused by the Hundred Years War meant the abbots had to finance the maintenance of the village fortifications, and the abbey started to decline.
According to tradition the abbey was the birthplace of the Blanquette de Limoux. During the 16th century, the monks elaborated a semisparkling wine which has become famous around the world.
During the 18th century, the French Revolution caused further financial problems for the Abbey and it was obliged to sell its land and possessions.
References:La Hougue Bie is a Neolithic ritual site which was in use around 3500 BC. Hougue is a Jèrriais/Norman language word meaning a \'mound\' and comes from the Old Norse word haugr. The site consists of 18.6m long passage chamber covered by a 12.2m high mound. The site was first excavated in 1925 by the Société Jersiaise. Fragments of twenty vase supports were found along with the scattered remains of at least eight individuals. Gravegoods, mostly pottery, were also present. At some time in the past, the site had evidently been entered and ransacked.
In Western Europe, it is one of the largest and best preserved passage graves and the most impressive and best preserved monument of Armorican Passage Grave group. Although they are termed \'passage graves\', they were ceremonial sites, whose function was more similar to churches or cathedrals, where burials were incidental.
