Consecrated in 1175, this church is a superb example of Italian Romanesque art, particularly the apse and lateral façade. The rows of blind arches and the series of fine columns suggest the influence of Lombardian and Tuscan artists. The interior has remnants of Byzantine-inspired Romanesque frescoes (12C) on the north side and in the side chapels. The white-marble Baroque high altar (1701) is graced with statues of the four saints protectors of Zadar: Chrysogonus, Simeon, Anastasia and Zoïle.
