It is unknown when Schuttbourg Castle was built, although some sources say it dates back to the 12th century. It was first mentioned in the 15th century. It was the possession of the Lords of Fischbach who later sold it to the Lords of Clerf.
In the beginning of the 20th century it was a ruin. In 1936 it became private property and was rebuilt into a youth hostel, which opened in 1939. In the Second World War the castle was damaged severely during the Ardennes Offensive. In 1950 these damages were repaired.
The castle is now still private property.
References: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.
