In the Middle Ages, Azille was one of the most important towns in the Archidiocese of Narbonne. In the 14th century the village supported the church of Saint Julien which was part of the chapter of Saint Just of Narbonne. There were also two convents: the Franciscans and the Royal Abbey of Saint Clare. Unusually, apart from the episcopal city, the town was the only one to have two parishes: Saint-Julien and Saint-André. The parish of Saint-André, which is known today only from ruins and the name of a quarter in the town, was united with Saint-Jacques-de-Béziers in 1096, then with the Abbey of Lagrasse in 1118, then finally with Saint-Sebastian-de-Narbonne.
