The cathedral is rich in sculptures from all epochs of its history. Warm, directed light from Oseris spotlights for low-voltage halogen lamps adds emphasis to the artworks and makes their vivid character better appreciable.

Last but not least is the daylight. The builders of the cathedral used it to bring their work to life: coloured by stained glass windows, speckles of light make their way through the room with the passage of the sun.
