Neuberg (also Neuberk) is a ruins of castle in Podhradí in the Karlovy Vary Region. The castle was built by the Neuberg probably in late 13th century, and was first mentioned in 1288. In that year, after Albrecht von Neuberg's death, King Rudolph I of Bohemia handed Neuberg and the whole village to the lords of Plauen as a fief. Later, the castle was damaged by the army of Charles IV. In 1392, the village and the castle were inherited by Zedtwitz, and became the centre of the whole Aš region.
After a big fire in 1610, the castle was seriously damaged. The House of Zedwitz divided into several lines that moved to new chateaus in Aš, Kopaniny, Doubrava, Smrčina and two chateaus in Podhradí. Since then, the castle has been uninhabited.
Nowadays there is only the castle tower, 22 metres high. The local council tries to save it, but due to lack of finances it is a big problem.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
