The Church of St. Lawrence was built in the 13th century, probably only after the foundation of the town in 1250. Construction works could last until the end of the third quarter of the 13th century. As early as 1285, there was a first record of the local priest Rudolf, who then appeared as a witness on the document.
In 1428, the Hussites plundered and burned down the church of which bare walls remained. The reconstruction continued with problems until 1472, when the church was re-consecrated. During it, a new, larger chancel was built.
In 1560, the church was damaged again by a fire, after which its facades were covered with Renaissance decorations (corner bossage) during renovation. The church survived in this condition until 1729-1733, when it was rebuilt in the baroque style at the request of the bishop of Wrocław, Francis Ludwik von Neuenburg. The old nave and the gothic chancel were almost completely rebuilt, the older walls were dismantled and only partially used in new building. In 1841, two early modern helmets were erected by the carpenter Francis Berger on the western towers, and at the same time the front wall between the towers was raised to the height of the crowning cornice. The helmets of the towers were replaced once again at the beginning of the 20th century.
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.
