Dubrovnik. Filled with ancient stone buildings, narrow cobbled streets, and fortified ramparts rising above red-tiled rooftops. Stradun is the city’s focal point and main artery. Whilst Dubrovnik’s streets are blessedly free of traffic. A UNESCO World Heritage Site, the old city remains the pride of the Republic of Croatia and houses the world’s oldest pharmacy. Lantern-lit limestone alleys, pealing bell towers, and russet rooftops, ancient Dubrovnik remains a show-stopper. From May to September, you’ll find yourself jostling through crowds along its beautiful Stradun (the main promenade, in ivory-white limestone) and towering city walls.
