Dubrovnik City walls are the most important feature of Dubrovnik and a world renowned iconic symbol of the white stone beauty, therefore the main reason why Dubrovnik is now known as the Pearl of the Adriatic.
Dubrovnik City walls run uninterrupted for 1940 meters encircling the City. The City of Dubrovnik is completely surrounded with defensive walls and forts, including the Old Port.
The walls were built systematically throughout history especially in difficult times when permanent danger of foreign attacks lured over the Dubrovnik Republic, and the walls have been preserved to the present day and are still functional, not only because of the proficiency of their skillful builders, diligence and care of the Dubrovnik citizens who maintained them and built upon them as necessary, but also because of the splendid ability of the skilful Dubrovnik diplomacy.
The history of the fortifications goes back to the early middle Ages. The whole city was enclosed with walls in the 13th century, except for the Dominican monastery, which came under the City wall complex only in the 14th century.
The average thickness of the wall was 1.5 meters (5 feet), and it was built of stone and lime. To increase the strength of the walls and reinforce defensive position, 15 square forts were built in the 14th century. Extensive work was done on the walls towards the close of the 14th century, at the time of the final liberation from the Venetian supremacy. The design of the walls derives from the 14th century, while the definite shape was fixed in the period which is, not without reason, referred to as the Golden Age of Dubrovnik, from the fall of Constantinople in 1453 until the devastating earthquake of 1667.
The main wall on the land side is 4 to 6 meters thick, but narrower on the side facing the sea 1.5 to 3 meters thick. Its height reaches 25 meters in some places. The wall on the land side is protected by an additional scarp wall as a defence against artillery fire.
The irregular quadrilateral formed by the walls is protected at four prominent points by strong forts. The strong round Tower Minčeta is to the north, the port is protected by the detached Fortress Revelin in the east and by the big complex of the Fortress of Saint John in the south-east. The western entrance to the city is protected by the strong and beautiful Bokar fortress. The western end of the city is also protected from danger from the sea and land by powerful detached Fortress Lovrijenac. In addition to these strong and prominent fortifications, the city walls are protected additionally with 2 round towers, 12 quadrilateral forts, 5 bastions and 2 corner towers, while the scarp wall is flanked by one large and 9 small semicircular bastions.
