Besides the monumental 17th century Renaissance chateau with an
English-style park (a rebuilding of original Gothic castle), the most
significant sight is the town square, a unique complex of long urban
plaza with well-conserved Renaissance and Baroque houses with high
gables and arcades; since 1992 all of this has been a UNESCO World
Heritage Site.
The Gothic castle was built in the second half of the
14th century. At the end of the 15th century the castle fortifications
were strengthened and a new gate-tower built. In the middle of the 16th
century the medieval castle no longer satisfied Renaissance nobleman
Zacharias of Hradec, who had the castle altered in the Renaissance
style. The ground floor was vaulted anew, the facade decorated with
sgraffito, and the state apartments and living quarters received stucco
ornamentation together with trompe l'oeil and chiaroscuro paintings in
1553. The counter-reformation brought the Jesuits to the town, who built
the church of Name of Jesus in 1666-1667, according to the plans of
Domenico Orsi. The column of the Virgin and the fountain in the centre
of the square date from the 18th century
