Originating in the old nave, an elaborate ascent flows into the new section of the building, connecting the two big rooms with each other and creating a new joint focal point: the sanctuary. Embedded in the sanctuary are the liturgical objects made of dark rock. In the annex, the ascent creates a special space adorned with saintly figures. The ensemble proceeds to the rear of the sanctuary, where it forms the staircase for the choir.
The steel beams, which used to spatially separate the old from the new section, were removed. The view on the joint sanctuary is unburdened and both rooms merge into a whole. The entire floor of the church is newly covered in pale limestone. The dark expansion joints form a web throughout the church, carrying on the alignment of the stairway ensemble.
