Rømø church was built around 1200 but extended in the 17th and 18th centuries when the island prospered due to whaling. The church is consecrated to the patron saint of sailors, St. Clemens and many ship models, donated by seamen, are hanging in the church. During the last century, rights to have one's name on a church pew were sold, the proceeds being used for church expenses, and many of these can be seen on the pews in the church today. Very interesting churchyard with old headstones of the ship commanders and their families, British and German pilots from World War II.
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.
