In the northern transept stands a Renaissance altar made from sandstone and alabaster dedicated to Bernard of Clairvaux, created in 1625/6 by Veit Dümpel. To the right of this altar is the entrance to the "Michaeliskapelle" with three altars dedicated in 1207 that survived the redecoration of the church. The chapel combines late Romanesque and early Gothic features. Since the axis of this chapel and the crypt below are not aligned with the rest of the church, these may be the oldest parts of the structure, begun before the plan for the overall basilica was finished.
