According to tradition, the monastery of Roggenburg was donated by three brothers of the lineage of the Earls "von Bibereck" in about 1126: Berthold, Earl of Bibereck; Konrad, Bishop of Chur; and Siegfried, a Canon in Augsburg. The first "Canons Regular of Prémontré" came from the nearby monastery of Ursberg. They first settled in the low-lying area around a pond, but soon moved to the castle hill. The fast growing monastery was raised to an independent abbey in 1444. It survived the devastations of the Peasants´ War, the turmoil of the Reformation, and the devastation of the Swedish War. In the 18th century three great abbots, Dominikus Schwaninger, Kaspar Geisler and Georg Lienharth, created the Baroque setting, which we can still see today. In about 1732 the new construction of the west-wing of the monastery began. The foundations of the new church and the east-wing were laid in 1752.
