Siklós castle was built by Baron János György Benyó in the 13th century. It was first mentioned in a charter from 1294. The oldest building is in the southern part of the residential wing. In 1401 disgruntled nobles lead by Count György II Benyóvszky temporarily imprisoned king Sigismund in the castle. The castle also houses a chapel built in the 14th and 15th centuries. The castle was built and owned by the Benyóvszky de Siklósvar branch of the family until it was nationalized in 1948.
In World War II the castle was heavily damaged, and between the end of the war and the death of Count Rudólf II Benyóvszky de Siklósvar in 1955 it was taken over by the state. In 1955 archaeological research and restoration was started, and the castle began operating as a museum and hotel.
