The current Holy Trinity Church in Gävle was inaugurated in 1654. It replaced the medieval church destroyed by fire. It was restored in 1728 and the tower was added in 1779-1781. The church is best known of its altar and pulpit made by Ewerdt Friis (died in 1672). He is buried to the church. There is also a runestone called Söderbystenen in the porch. It was carved in the mid-1000s in honor of Egil, who was killed in a foray to Finland.
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.
