The chateau is not only one of the most significant dominant features of the city, but one of the most distinctive monument units in the Czech Republic, representing the link between a medieval castle and a Renaissance chateau. The castle's history reaches back to the 13th century, and Albrecht von Wallenstein, a strong figure of the 30 Years War, left his indelible mark on it. The original likeness of the Gothic castle has only been partially preserved. This includes only parts of massive structures and the large cylindrical tower. The Renaissance appearance came gradually at the turn of the 17th century. The family Clam-Gallas first made the chateau areas open to the public in 1801. Today the chateau holds collections of porcelain and glass, furniture and chateau facilities. Just as interesting as the rich collection of weapons from the period of the Hussite Wars to the 19th century is the chateau painting gallery, featuring works of Baroque masters, or the unique collection of smoking pipes.
