After a thorough renovation carried out between 1999 and 2006, the castle was a major protocolary site during the 2008 Slovene presidency of the EU.

Its greatest asset is a set of frescoes by the baroque painter Franc Jelovšek, including an unusual depiction of a camel-riding Chinese tambourine player.
