Šibenik

The trademark of Šibenik is its Gothic-Renaissance cathedral, built of pale-gray Dalmatian stone and designated a UNESCO World Heritage Site, which stands on a raised piazza close to the seafront promenade. From here a network of narrow, cobbled streets leads through the medieval quarter of tightly packed, terra-cotta-roof houses, and up to the ruins of a 16th-century hilltop fortress. The city is worth at least a day of exploring, if only to get lost wandering through its time-smoothed cobblestone streets and wowing at its medieval architecture. More underrated—and therefore more peaceful—than some larger coastal towns, Šibenik is the perfect location for a romantic and peaceful getaway.
