Archeological investigations have shown that the Lauterstein castle was built in the second half of the 12th century. It was first mentioned in writing in 1304 when a document named a Johannis in Lutirstein of the ministerial family of Erdmannsdorf in the castle. Its purpose was the protection of a medieval trade route between Leipzig and Prague across the Ore Mountains.
The family of Schellenberg became lords of Lauenstein in the early 14th century. They lost their influence in 1323 after they lost a feud with Altzella Abbey, and margrave Frederick the Brave enfeoffed the burgraves Albrecht IV von Altenburg und Otto I von Leisnig, who had helped to support him and the abbey, with Lauterstein castle and the town of Zöblitz.
Kaspar von Berbisdorf from Freiberg, an owner of mines and metalworks in the Ore Mountains, bought the lordship of Lauterstein for 4000 guilders from burgrave Otto II of Leisnig and Altenburg in 1434. His descendants Bastian and Melchior divided the lordship and the castle in 1497 into Oberlauterstein and Niederlauterstein. A fire damaged the castle in 1530, but it was rebuilt within a few years. In 1559, Prince-elector Augustus forced the Berbisdorf family to sell castle and lordship Lauterstein for 107,784 guilders and installed the administration of a Saxon Amt in the castle.
According to local tradition, on 14. March 1639, three Swedish horsemen set fire to the castle. It was not rebuilt and has remained a ruin since then. The administrative seat of Amt Lauterstein moved to Marienberg and later to Olbernhau and Zöblitz.
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.
