The Altmünster abbey near Mainz, Germany, was reputedly founded by Saint Bilihildis (d. 734), who served as the first abbess; however, it may well be a 7th-century foundation. Though founded as a Benedictine abbey, it adopted the rule of the Cistercians in the 13th century. It was dissolved during the secularization of the 18th century, and the abbey buildings were demolished.
