 In the west, the monastery gate, a two-storey house for guests and lay brothers were added, built around the three-aisled Basilica with a three-apsed choir, a transept and a double tower facade to the west.The westerly courtyard was also built in the foundation era, preceded by a single goal, which was flanked by two chapels.About this door system, there was possibly the entrance to the Nellenburg Palatinate, once the residence of the family.
