The Church of Saint Demetrius of Thessaloniki in Veliko Tarnovo, Bulgaria, a medieval Bulgarian Orthodox church, was part of a monastery and played a role in the anti-Byzantine Uprising of Asen and Peter in 1185. Destroyed in the 13th century, it was reconstructed in the 1350s. Plundered in the 18th and 19th centuries, it was completely destroyed by an earthquake in 1913, leaving only the apse and fragments of frescoes. Reconstruction began in 1977–1985, led by Teofil Teofilov, based on architectural remains and examples from better-preserved Bulgarian churches. Two layers of frescoes, dating to the church's construction and the 14th century, have been preserved.
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.
