Ciborium
The apsis is dominated by the marble ciborium, modelled after the one in St. Mark's in Venice, it was built in 1277 on the orders of by Otto, Bishop of Poreč. The canopy, decorated with mosaics, is carried by four marble columns that belonged to the previous 6th-century ciborium. The front side of the canopy depicts representations of scenes from Mary's life, the Annunciation. In the 15th century Bishop Johann Porečanin ordered in Italy a Renaissance relief for the antependium of the altar, made of gilded silver. The polyptych of the Venetian painter Antonio Vivarini dates from the same period. The Last Supper, painted by Palma the Younger is a Baroque work.
