In the 18th and also the 19th centuries, the mansions Boštanj pri Sevnici (Savenstein) and Impoljca (Neustein) boasted designed gardens that may be ranked among the most important in Carniola. Particularly ambitious were the Baroque-style garden designs and their schemes have been preserved from the plans made at the beginning of the 19th century. Both gardens were most probably procured by the Mordax family, which owned the estates almost throughout the entire 18th century. In the 19th century, both gardens began to exhibit elements of a new landscape style. However, thanks to Ritter Ludwig Gutmannsthal-Benvenuti, only the one at Boštanj pri Sevnici found its expression as a classic landscape garden.
