Brief synthesisThe Historic City of Trogir on the eastern coast of the Adriatic is a remarkable example of urban continuity. The two ancient main streets, the cardo maximus and the decumanus are still in use. In terms of space and population Trogir is a miniature city, but its significance for the cultural and economic history of the Adriatic outweighs its restricted urban scale. Z-3249 of the protection of Historic City of Trogir imposes strict control over every aspect of development within the historic town. Controls over planning and regulation within the historic town come within the purview principally of the local authorities.
