The stretched Upper Church ends in the east in a polygonal choir. The high arch has a square profile, a sign for the romanic style. The slim semi-pillars in the six corners of the choir are in the early gothic style. They and the two others, on the north and south side, are decorated with palms and buds. This is supposed to liven up the room and make it light.

Traces on the ground hint to the ancient raised altar which was destroyed in the farmers rebellion. Above this you can see three wooden figures (late gothic): on the right hand side: Benedikt of Nursia, next to Mary with Jesus on her arm, and on the left the founder of the cloister Bernard of Cairvaux.
