Château de Larressingle was built in the second half of the 13th century. The second and third floors were added by Arnaud Orthon de Lomagne, Bishop of Condom, between 1285 and 1305. Windows were added at various times in the 15th and 16th centuries, particularly between 1521 and 1545 when extra works were carried out for Monseigneur de Grossolles, including the construction of a hexagonal tower.
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.
