Bogenšperk Castle is the successor of the medieval fortification Lichtenberg. The present name was brought to the castle by the Wagen family, and for two decades the castle was owned by the famous polymath and member of the English Royal Society Janez Vajkard Valvasor.
Here, among other things, the famous Glory of the Duchy of Carniola came into being, and in the graphic workshop countless copperplate engravings of Carniolan towns, market towns, monasteries and castles were produced. The Renaissance building with four towers and an arcaded courtyard, with its furnishings, preserves the memory of Valvasor's times.
In the castle today the collections of the Technical Museum of Slovenia, the Museum of Superstition, a collection of national costumes, hunting, geodetic and geological collections, Valvasor's study and the copperplate printing works are on display.
