 A further expression of this change is the reform of the abbey which was completed with the replacement of Abbess Christina Strölin (1469–84) by the reform-oriented Abbess Elisabeth Reichner (1484–1508/13) and the rebuilding of the abbey under the latter when not only the ecclesiastical buildings were either rebuilt or renewed but also had a wall surrounding the monastery added.During the Protestant Reformation Söflingen Abbey came into conflict with the Imperial City of Ulm which had accepted Protestantism in 1529.The abbey endeavoured to defend Catholicism and to preserve its political independence.
