The Republic of Venice made Koper the regional capital during the 15th and 16th centuries, and the magnificent architecture of the Old Town bears witness to the spirit of those times.The most important buildings are clustered around Titov trg, the central town square. Here stands the Cathedral, which can be visited daily from 7 to noon and 3 to 7, with its fine Venetian Gothic facade and bell tower dating back to 1664. Across the square the splendid Praetor's Palace, formerly the seat of the Venetian Grand Council, combines Gothic and Renaissance styles. From the west side of Titov trg, the narrow, cobbled Kidriceva ulica brings you down to the seafront.
