Some of Croatia’s best known sights are truly astonishing, although with the country’s fascinating history and mix of Roman, Greek, Croatian, Venetian, Ottoman, and Austro-Hungarian rule over the years, it is hardly surprising. From the wonderful Old Town in Dubrovnik, to the fantastically well-preserved Roman amphitheater in Pula (the Arena), to Roman Emperor Diocletian’s Palace in Split there is plenty to see and do.
