The inner shield is based on the coat of arms of the diocese of Münster, a red bar on golden ground.

In the upper left corner of the inner shield is an eight-cornered star, resembling the Octagon of the Aachen Cathedral as well as the eight regions of the diocese.

The red rose in bottom both symbolizes the hometown Rosendahl of the bishop, but also Mary, patron saint of the cathedral, town and diocese of Aachen.
