Tarant noble family founded Tarantsberg castle in 1217, later named as Dorenberch and Dornsberg. The St. Ursula chapel was probably built between 1270 and 1280. From 1699 the castle has been owned by the counts of Mohr, Giovanelli and Fuhcs families.
After the end of WWII the building was damaged, but in 1964 the Gottschall family from Munich purchased the castle complex and had it restored with the utmost effort. Still today this castle is in possession of this family and cannot be visited.
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.
