Bogenšperk Castle is considered to be one of the most beautiful castles in Slovenia and one of the Slovenian inhabited areas' most important cultural monuments. It was built in the first half of the 16th century. In 1672 it was purchased by the famous Slovenian polyhistor and scientist Janez Vajkard Valvasor (1641-1693), who wrote his best known work, The Glory of the Duchy of Carniola (Slava vojvodine Kranjske, 1689), while living there. Apart from Valvasor's study, printing workshop and Slovenia's main geodetic collection, visitors to the castle's museum can view a collection of mineral rocks and several collections dedicated to superstition, Slovenian national costumes and hunting.
