Once the Cathedral building was restored following its war-time devastation, a search was launched for objects suited for its decoration. The search turned up a Gothic gilded pentaptych (an altar composed of a middle section and two pairs of wings). The piece dates back to 1512 and features 15 female figures. At its centre is the Madonna with child, being adored by angels. Next to her are St. Barbara and St. Catherine. During Lent, the altar is kept half-closed to reveal eight scenes from the Passion of Christ. On Good Friday, in its fully closed position, the altar reveals four paintings depicting Sts. John, Jerome and Christopher. The predella, i.e. the base of the altar, portrays a scene from the Last Supper.
