The urban structure dates from the time of the town’s greatest economic growth, under Venetian rule. As in many coastal towns, the square is also a port. Here one finds the city hall to the west and the stock market to the east. On the northern side, the church of St. Nicholas has the highest bell tower on the Adriatic coast. A so-called ‘balota’ stone marks the place where the port-square ends and where the church square begins, proving that the way the space was structured was very important for the community.
