Kornberg Castle is located near Dörfl (municipality of Riegersburg), in south-east Austria in Styria.
Kornberg Castle was first mentioned in a document in 1284. It was built by the Lords of Kornberg - on behalf of the Knights of Riegersburg-Wildon - to secure access to the Riegersburg. The strategically favorable, elevated castle was additionally secured by a fortification wall. Originally it was not used as a residential palace, but as a fortified complex. In the course of securing the border region against Hungary, numerous colonists from Lower Austria were settled and castles were founded in the 12th century.
