The Sacred Collection encompasses artefacts, paintings, sculptures, liturgical vessels, books and church vestments. The oldest exhibit is the bronze bell from 1479 adorned with bas-relief medallions which depict the Crucifixion and Annunciation. The Collection keeps several chalices, monstrances, ciboriums, altar crosses. Some of the chalices were made in Venetian goldsmith's workshops of the 17 and 18 centuries, whilst the majority of them were made in local workshops.
