Inaugurated by the count of Foix Roger III, the abbey of Boulbonne was founded in Mazères in 1129. The abbey takes its name from the lush forest of Boulbonne, located between Cintegabelle, Mazères and Pamiers. In 1150, the Benedictine monks of the abbey, like many at that time, joined the Cistercian order. During its development, the abbey of Boulbonne hosted, among other things, the ecclesiastical beginnings of Jacques Fournier, who became Pope Benedict.XII in 1334.
During the revolutionary period, the abbey of Boulbonne was no exception to the destruction and two thirds of the building disappeared. As for the furniture, it was found scattered throughout the region. But one can find for example at the church of Cintegabelle, the magnificent organ of the old church of the abbey of Boulbonne.
