The church of the Assumption of the Virgin Mary was built during Romanesque time, in the 12th and 13th century. Originally, the church had three naves, with three prominent apses on the east. Still, the parts of pre-Romanesque church furniture, dating between the 8th and 9th centuries, walled into the façade and in the church, witness its earlier emergence. There is a particularly prominent rosette by the local master Sinog on the church façade. The construction activities during the Renaissance and the Baroque, i.e. from the 16th until the 18th century, changed the interior of the church by adding side chapels on the northern and southern side. In the 17th century, the original semicircular central apse was transformed into a rectangular one.

Just like most littoral villages, the bell tower leaning against the parish church dominated the view of the city. Its construction started in 1533 and lasted three years. The oldest bell in the bell tower, called St John, dates from 1561.

The church preserves a valuable Renaissance and Baroque furniture, and along with a Renaissance wooden reredos on the main altar, there is a prominent wooden triptych on the side altar showing St John the Evangelist from the 15th century by the Venetian master Jacobello del Fiore. Around the central figure of St John the Evangelist, there are six smaller paintings with details from the life of the saint.
