The shrines that hold the Cathedral’s treasure shine. Visiting the rooms is like travelling back in time and reliving a never forgotten past. The crown, three gold rings with precious stones and a plaque found in the tomb of Frederick II’s first wife, Constance of Aragon, can still be admired today. There are also: an ivory shrine; two polygonal medallions; a silver and gilded bronze shrine; a silver chalice; a gilded bronze and pierced silver shrine from the Gothic period; the Carondolet antependium in silk, velvet and gold; the Peace of St. Luke; the chalice of Charles III of Spain; an embossed and chiselled silver shrine containing the wood of the Holy Cross; the Barbavara chalice and the Soledad chalice.
