Currently 16 Cistercian Monks of the Strict Observance.

In 1046, Heilwige of Dabo, the countess of Eguisheim and mother of Pope Leo IX, founded on the hill (berg), along a stream (oelen), a priory of regular canons of Saint Augustine.
Very prosperous in the 13th century, the monastery was left in ruins by wars of the 14th century. Its decline continued until the 16th century. In 1626, the abbey became a property of the Jesuit college of Freiburg im Breisgau, then it belonged to the University of this same city in 1774. At the time of the French Revolution, the abbey buildings were sold to a industrialist from Mulhouse.
In 1825 it came back into the hands of an group of reformed Cistercian monks commonly called "trappists".
The monks started farming the land. They went through difficult times: famine in 1846, fires and epidemics. Nevertheless the monastery grew.
The monastery owns a large library with more than one hundred thousand books.
