The group of religious monuments in Porec, where Christianity was established as early as the 4th century, constitutes the most complete surviving complex of its type. The basilica, atrium, baptistery and episcopal palace are outstanding examples of religious architecture, while the basilica itself combines classical and Byzantine elements in an exceptional manner.
Trogir is a remarkable example of urban continuity. The orthogonal street plan of this island settlement dates back to the Hellenistic period and it was embellished by successive rulers with many fine public and domestic buildings and fortifications. Its beautiful Romanesque churches are complemented by the outstanding Renaissance and Baroque buildings from the Venetian period.
