Dubrovnik, the beautiful Adriatic Pearl of Dubrovnik, is a popular tourist attraction for many people. Dubrovnik Old Town and a large part of the city walls were listed on the UNESCO World Heritage List in 1979. It is the defensive stone wall around the old city that is 1940 meters long. The security of the old city is the largest and most complete city wall in Europe. The main entrance is 150 kuna next to Inner Pile Gates. It takes about 60 minutes to board the city wall. The stone wall trail is very wide. Visitors stroll endlessly. The 360-degree view on the wall of the old city has a panoramic view of the high and low undulating red roof distant mountains offshore fishing sails dotted with white clouds and blue sky and the sea at the junction of the sea and the sky up to 25 meters. The beauty of the sea and the sky is even more refreshing.
