An attractive Romanesque cathedral - the biggest in Dalmatia - built during the 12th and 13th centuries. As with many Dalmatian churches, the belfry is separate. You can climb to the top - the view is amazing. Two attractive rosettes decorate the front portal, and a gallery of blind arches the flanks, with a ledge above them providing seating for pigeons to look down on the throngs on the Kalelarga. Simple stone blocks are lightened with decorative friezes, and the lovely stonemasonry around the doors is worth a careful look. Highlights of the interior include the stone ciborium covering the high altar, frescoes, an intricately carved choir and an Early Christian mosaic in the sacristy.
