Trogir is a small medieval city built on a tiny island connected by bridges to the mainland and to the larger island of Čiovo, about 30km west of Split along the coastal highway. Its UNESCO-listed old town is a remarkable concentration of Romanesque and Gothic architecture: the Cathedral of St Lawrence with its extraordinary Romanesque portal carved by Master Radovan in 1240 is the finest medieval sculpture on the Adriatic coast; the Riva waterfront, the Kamerlengo fortress, and the town loggia are all in excellent condition.
The whole old town can be walked in an hour or two; the combination of quality and compactness is unusual. Most visitors come as a day trip from Split, which is half an hour away by bus or organised tour. The summer crowds are considerable but manageable on weekday mornings. Trogir has fewer visitors than Dubrovnik but arguably more concentrated architectural quality per square metre than anywhere else on the Dalmatian coast.
