Trogir is an excellent example of urban continuity. The orthogonal street plan of this island settlement originates from the Hellenic era – consecutive rulers continued to decorate it with exceptional public and residential buildings and forts. Its beautiful roman churches are supplemented with exceptional renaissance and baroque buildings. The most significant building is the Trogir Cathedral with its west portal, a masterpiece of Radovan and the most significant example of roman and gothic art in Croatia.
