the church houses the Zadar Polyptych, an early work by Venetian painter Vittore Carpaccio. The bell tower was built in two stages. The ground floor and first floor were built in 1452 during the reign of Archbishop Vallaresso, while the upper floors date from 1890 to 1894 under design by the English architect and art historian Thomas Graham Jackson. The three upper floors, with four sides, are decorated with double mullioned windows. A flat wall surface is stylized with a floral mosaic, while the wreaths that separate floors are highlighted with a fretwork. At the top is an octagonal pyramid with a brass statue of an angel which rotates according to the direction of the wind.
