The Gothic fortress was changed during the Renaissance era and then in the 19th century within the "Tudor Gothic Passion" period. The last owners of the castle, the Buqouy family (who were Czech nobles of French origin), transformed it into a museum open to the public, one of the first museums in the Bohemian land. The main palace, with its architectural features of several historic styles, shelters a unique collection of Baroque furniture and paintings as well as a wonderful Renaissance Hall with a famous "musical niche" in the so-called Knight's Hall. The message "Loves disappear, colours fade" was discovered in 2004 carved on a wall in the Knight's Hall. This was done by Spanish soldiers in the 17th century.
