Classed as a world heritage treasure by UNESCO, Dubrovnik is a place of ancient streets lined with stone palaces, Venetian-style buildings and bell towers. The city is enclosed by stone walls, and the highlight is a leisurely walk atop these massive walls for a great view of the city and the sea. Entering Dubrovnik, you are greeted by an impressive pedestrian promenade, the Placa, which extends before you all the way to the clock tower at the other end of town. The Orlando Tower here is a favorite meeting place. Just inside the city walls near the Pile Gate is the Franciscan Monastery housing the third-oldest functioning pharmacy in Europe, operating since 1391. For a fantastic panorama of the city, take a cable car ride to the summit of the 1,340-foot Mount Srdj.
