Work on the Shrine concluded around 1220 with the reliefs and decorations on the back, done by goldsmiths from the Meuse area. The space is divided into two shrines below and one above. The theme of the bottom level is the Passion of Christ, which has to be seen as a continuation of the lost cycle from the lower roof surfaces. In the gable is Christ crowning the martyrs Felix and Nabor, completing the Apocalypse scenes formerly on the upper roof surfaces.
