Schloss Bleiburg is a Renaissance castle in Carinthia whose core dates to the early 12th century, later transformed into its current Renaissance style in the early 17th century. Owned by the aristocratic Counts Thurn-Valsassina family, the castle is notable for hosting preliminary negotiations during World War II and now serves as a cultural venue hosting summer guided tours and castle concerts. The estate also provides a scenic backdrop for regional leisure facilities and remains an important landmark in the Austrian-Slovenian border region.
