 During the Middle Ages the monastery not only owned possessions in the vicinity of Söflingen and Ulm but also had ownership over numerous villages stretching as far as Gomaringen near Tübingen and, transcending the boundaries of the Diocese of Constance, even into the Diocese of Augsburg.Since 1239 Söflingen Abbey owned vineyards in Neuffen and later acquired vineyards in Heimbach, Beutelsbach, Großheppach, Schnait (all near Weinstadt) and Stuttgart.With the acquisition of the local fortress, a process began which culminated in the whole village of Söflingen coming into the possession of the abbey around 1270.
