In the middle of the botanical park stands a fine neo-Renaissance country house (19C) built for the Tiskevicius family, now home to an exhibition dedicated to the gold of the Baltic. Visitors learn about the different forms and colours of amber. Three rooms focus on plants and animals preserved in it; others deal with the various parts of the world where amber is found, trade routes and its usage through the ages (crafts, jewellery, medicine). The visit ends with works by contemporary sculptors.
