Dubrovnik is a medieval city with a medieval infrastructure, street network and – most important – the medieval city walls. The main attraction of Old Town Dubrovnik (the City) apart from its old monasteries and beautiful palaces are the ancient City walls with its intricate and complex system of forts, bastions, casemates, towers and detached forts. 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.
