Is an outstanding and immaculately preserved example of the arcade castle, a type of building first developed in Italy and modified in the Czech lands to create an evolved form of special architectural quality. The main external feature of the castle is the sgraffito decoration: what look from a distance like bricks are in fact designs made from etching away plaster to reveal the undercoat. Each design is different and the centres contain many different images, from leaves to people. A highlight of the interior is the preserved baroque theatrette, which is one of only five left in the world. The castle was the birth place of composer Bedřich Smetana, and the rooms in which he spent the first years of his life are open to the public.
