No visit to Dubrovnik would be complete without a walk around city’s main claim to fame – spectacular city walls. Built in the 10th century these enormous walls, as high as six meters and up to six meters thick, provided a solid defence against invaders. With nearly 2 kilometres in length, these city walls offer a perfect spot for a casual stroll and mesmerizing views of Old Town and shimmering Adriatic. Other highlights include its two towers, the Min-eta Tower and the Bokar Tower, along with two forts, the Fort Lawrence and the Revelin Fortress. There are three access points to the walls: one close to the Dominican Monastery, one close to the Maritime Museum at Fort St. John and one at Pile Gate.
