Bizeljsko Castle (Slovenian: grad Bizeljsko; grad Orešje, German: Schloss Wisell) is a castle in Bizeljska Vas, a village in the Municipality of Brežice, in southeastern Slovenia. It consists of a residential part that forms the centre of the complex and includes a Baroque chapel, as well as an outer part that served a defensive purpose.[1]
The castle was mentioned for the first time in written sources in 1404. It has belonged to the families Tattenbach and Windisch-Graetz, among others. The oldest parts of the now-visible structure date from the 14th century, and the castle has been rebuilt and expanded gradually over the centuries.
