Kunšperk (pronounced [ˈkuːnʃpɛrk]; German: Königsberg[2][3]) is a settlement on the right bank of the Sotla River in the Municipality of Bistrica ob Sotli in eastern Slovenia.

The architecture of the town today shows Classicist and Biedermeier features, as well as the work of local 18th- and 19th-century stone cutters.

Saint James' Church was abandoned under the rule of Joseph II and demolished, and a blacksmith's workshop was built in its place.

[5] A third church, dedicated to Saint Catherine, stood in the settlement above Orešje na Bizeljskem near Kunšperk Castle.

It was a Romanesque castle surrounded by defence walls built in the 12th century with later additions (a Gothic chapel and Renaissance fortifications).
