Īvande Manor, also called Lielīvande Manor (Schloß Groß-Iwanden) was built in the second half of the 19th century according to a design by architect Teodors Zeilers. It was severely damaged by fire in 1905, but later repaired in 1912-1913. Unusual to estates in Latvia, an earlier 18th century manor house still stands nearby.
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.
