The old town of Kotor is one of the best-preserved medieval towns in this part of the Mediterranean. It was succeeded in preserving its original form, so typical of towns between the XII and the XIV century. The asymmetric structure of the narrow streets and squares, combined with the numerous valuable monuments of medieval architecture, contributed to Kotor being placed on UNESCO’s “The world natural and cultural inheritance” list. The cultural inheritance of this town is enriched by the unique architectural styles and the ambient atmosphere. The fortification system of Kotor, which protects it from the sea, is actually a wall 4.5 km long, 20 m high and 15 m wide, and is preserved as one of the world’s historic values.
