Counts of Celje
The castle ruins of Rabensberg Castle (, ) are in Rupe. The castle was built in the 12th century by the Knights of Rabensberg, the ministeriales of the Diocese of Gurk. In the 1370s, it became property of the Lords of Ptuj, and in 1438 it was inherited by the Counts of Schauenburg, the adversaries of the Counts of Celje. In 1452 the Counts of Celje burned it.
