Herceg Novi was founded (on a former small fishing village, existing since Roman Empire times) as a fortress in 1382 by first Bosnian King Stjepan Tvrtko I and was called Sveti Stefan or Castelnuovo. The Turks conquered Herceg Novi in 1482, and ruled for 200 years, until 1687. However, there was a short pause between 1538 and 1539 when it was held by the Spaniards before they were defeated in the Siege of Castelnuovo. Turkey ruled again until 1687, from then until 1797, the town was ruled by the Venetian Republic.
The Herceg Novi old town is amazing. It is on a fairly steep hill that leads all the way down to the sea. Wandering through the small stairways to the various plazas and fortresses is a many hour adventure. There are both Orthodox and Catholic churches that are well worth visiting.
Herceg Novi has two town squares, including the small, stone-paved Belavista (nice view), which is easy to get to from the main town square, Trg Nikole Đurkovića, once referred to as Salt Square, by walking up the stairs that lead through the town’s clock tower. Here, old stone buildings encircle the delightful church St. Arhangel Mihailo, a building unique in its architecture. This Orthodox Church is neo-Byzantine styled with Gothic and Romanesque details.
The Kanli Kula fortress dominating the old town doubles as an open-air theatre and is worth visiting mainly for the splendid views of the town and the Kotor bay.
The Spanjola fortress located higher up the mountain dates back to 16th century. Take a small street going upwards across from the Kanli Kula fortress.
The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
