The Irings established their fiefdom in the Loisach valley. It covered an area from Herrenhausen to Lake Starnberg and from Wolfratshausen to the fief belonging to Benediktbeuern Abbey. The castle built by the Irings, Iringsburg, gave the community its name.
Albert von Iringsburg, as a follower of Emperor Henry IV, was anathematized by Pope Gregory VII. To atone for her father and husband, Berta von Iringsburg and her sons Otto and Eberhard founded an Augustine monastery in 1121, which is now in the hands of the Salesians of Don Bosco. The abbey administered all church possessions in the whole fiefdom.
