Croatia, nestled along the shores of the Adriatic Sea, offers historic towns, picturesque coastlines and Renaissance and Gothic architecture. Trips here often feature the ancient walled city of Dubrovnik, a UNESCO World Heritage Site with a rich multicultural heritage. Highlights include the city's bastions and fortress; Onofrio's Fountain, built in 1438; the Franciscan monastery, with a pharmacy in operation since 1391; and many museums, galleries and churches.
Many itineraries also visit Split, where the fourth-century Roman emperor Diocletian built an immense palace. Zagreb, Croatia's capital, dates to 1094 and is home to St. Mark's Church, the Presidential Palace and the Croatian parliament.
