In 1815 the monastery was refounded by Trappists led by Pierre-François de Paul Malmy (Père Étienne) coming from La Valsainte, an abbey in Switzerland under the leadership of Augustin de Lestrange and under pursuit by revolutionary forces at the time. The new foundation flourished, and by 1850 had 233 monks.

The thriving Trappist community was able to found several other monasteries. In 1843 a Trappist community was established at Staoueli in Algeria, later Abbey of Our Lady of Atlas, which in turn gave rise to two communities, Notre-Dame de Tibhirine, at Tibhirine in Algeria, and Notre-Dame de l’Atlas au Maroc, at Midelt in Morocco. Aiguebelle also founded a community at Koutaba in Cameroon.
