The Church of St. Lawrence in Mynämäki is the second biggest medieval church in Finland. The sacristy, oldest part of the church, is dated back to the 13th century. The church itself was quite probably erected in the beginning of 15th century to replace the previous wooden church. It was expanded in 1600s and again in 1770s.
There are couple of old artefacts inside the church, for example wooden epitah from year 1624 and memorial of Fleming noble family also from the 1630s. Finnish National Board of Antiquities has named the church site as national built heritage.
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.
