The Angevin-Aragonese castle in Agropoli has a triangular shape with three circular towers and stands on the highest point of the headland. Around the walls there is a wide and deep moat which today is visible just on the side of the village and disappears while on the eastern side because of agricultural works and past landslide.
The castle was built on the 6th century Byzantine foundations by the Aragonese reign in the 15th century. The Inside part of the castle is composed of a central square, nowdays used as on open air theater, and on the northern side by the “French Room”.
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.
