It was founded in 1148 under the patronage of Alfant, bishop of Cavaillon, and Ramon Berenguer II, Count of Barcelona, Count of Provence, by Cistercian monks who came from Mazan Abbey in the Ardèche. Temporary huts housed the first community of impoverished monks. By 1152 the community already had so many members that Sénanque was able to found Chambons Abbey, in the diocese of Viviers.
