The Sånga church has been mentioned first time in 1308, when madame Ingeborg donated her land property to the church. The church was however built already in the late 1100s and enlarged in the 14th century.
The church has interesting mural paintings made around 1470. There are for example humorous paintings displaying events of Holy Bible. Also the pulpit, made in 1635, is richly decorated.
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.
