The monastery was founded in 1147 under the auspices of the first Cistercian pope, Eugenius III. The main church, built in a style transitional from Romanesque to Gothic, was consecrated in 1178 by Arnold, Bishop of Speyer. A number of other buildings — infirmary, refectory, cellar, auditorium, porch, south cloister, hall, another refectory, forge, inn, cooperage, mill, and chapel — followed in the course of the 13th century. The west, east and north cloisters date back to the 14th century, as do most fortifications and the fountain house.
