The manor comprises two building tracts and their basements; the northern tract had open arcaded passageways on the ground and first floors, dating to the 17th century. The surrounding grounds contain once-rich garden with botanically-interesting tree species and shrubs, two ponds and several associated buildings, such as gardening outbuilding with Orangery, now mostly deserted or serving other purposes. The park once also featured a decorative straw-roofed rustic farmhouse, for children to work and play.
History
First manor below Mount Konjice Konjiška gora) was mentioned as early as 1362, held until the 17th century by the barons Trebnik, who sold it to the counts Tattenbach. Today's manor was built between 1630 and 1636 by Johann Christoph von Tattenbach. After Tattenbach's the manor was owned by kaiser and then the Žiče Charterhouse till abolition of monastery in 1782. Beside counts Tattenbach the most famous owners of the Mansion were Princes of Windischgrätz, nobles who used Trebnik as their summer residence. The family remained its owner until the end of World War II when the manor was nationalised by the state. In the post-war period, the manor was used for various purposes, it included an inn, kindergarten, a home of elderly people, a music school, and so on. Similarly, like other historical building heritage in Slovenia was not properly maintained. In 1996, it was transferred from the municipal property to the property of a company that undertook to renovate it, but did not have any interest or assets, but even burdened the real estate with bank loans and mortgages, leaving the manor almost to collapse, until the ownership and renewal in 2012 was taken over by the Municipality of Slovenske Konjice.
