Castles in Croatia

Croatia's medieval fortifications are among the most dramatic in Europe. The walled city of Dubrovnik — the Republic of Ragusa — maintained independence for 450 years through brilliant diplomacy and civic innovation. Along the Adriatic coast, Venetian-built fortresses guard every headland, while inland, the continental castles of Trakošćan and Veliki Tabor rise from the forested hills of Zagorje.
