The city walls, the symbol of Dubrovnik, reached their full extent of 1.3 miles between the 11th and 13th centuries, essentially shaping Dubrovnik into its present-day look. Made entirely of stone, these walls—an immense system of forts, bastions, and walkways—were intended to protect the city from war and epidemics. Conquering them today requires just a walk to witness inspiring panoramas of red-tiled rooftops, pine- and cypress-shaded hills, and the blue Adriatic in the foreground. Their continued existence is a tribute to the impressive skill and architectural mastery of the city’s creators. For easiest access, enter the walls by the Maritime Museum in the fortress of St. John, or on the east side of the city, from the road to Ploče Gate by St. Luke’s church. With three entrance/exit points, you can choose how much and which part of the walls to see. Just don’t, under any circumstances, forget your camera.
