The origins of the abbey of Alet-les-Bains are unknown other than that of a priory in the eighth century. It was likely founded by Béra, viscount of Razés. By the twelfth century, it had much influence and many pilgrims. In 1318, the abbey became a bishopric in order to continue the fight against the Cathars; as it stayed until the French revolution. The diocese had eighty Parishes and spanned from Formiguères to Saint-Paul-de-Fenouillet. A wall, with four gates, built in the twelfth century to protect the abbey can still be seen today. In the sixteenth century, during the wars of religion, the Huguenots burnt and destroyed the abbey. In the seventeenth century, Nicolas Pavillon, bishop of Alet who stood up against the government of Louis XIV; could have found the means to repair the abbey, but did not feel that given the poverty of the people in his diocese, it would be acceptable. He did, however, build a bridge that spans Aude, in 1662 and gave an improved system of irrigation, as well as a seminar. The thirty-fifth and last bishop of Alet, Charles de la Cropte de Chanterac, who opened the "Grande route" Limoux-Quillan, also built a new portion of the bishopric, which he attached to the oldest part of the bishopric, which dates from the twelfth century and is now preserved. By climbing a flight of stairs, one would come to the first floor where one can see the beautiful and large synod hall as well as the library. The bishopric and its three hectares of gardens span a large portion of the old abbey. By the separation of church and state, the bishopric became the property of the persons who lived in his estates, which were dispersed around the region. The buildings were used until the beginning of this century. In the 21st century many British people moved to Alet.
