The original Gothic fortress from the end of the 15th century was rebuilt into a Renaissance residence in the second half of the 16th century, and then baroque rebuilt in 1766–1769. It has an atypical floor plan with a triangular courtyard with arcades. The valuable equipment of the original interiors with a picture collection, armory and library has been preserved. The castle houses the regional museum and its premises are also used for cultural and social events. The castle includes a castle park from the 16th century, on an area of more than 2.5 hectares. In the park there are the remains of the town fortifications, a salla terrena from 1894, and eleven sandstone sculptures from the turn of the 18th and 19th centuries.
