The Sponeck castle was built in the late 13th century to the site of late Roman fort (built by Emperor Valentinian I around 365 AD). The castle was destroyed in the Thirty Years War. After several changes of ownership the painter Hans Adolf Buhler acquired it in 1917, rebuilt and set up a studio in the former residential tower. After the painter's death in 1951 the castle was owned by the family. Today the stone wall and two corner towers are preserved of an original Roman fort.
The Jan Hus Memorial stands at one end of Old Town Square. The huge monument depicts victorious Hussite warriors and Protestants who were forced into exile 200 years after Hus, and a young mother who symbolises national rebirth. The monument was so large that the sculptor designed and built his own villa and studio where the work could be carried out. It was unveiled in 1915 to commemorate the 500th anniversary of Jan Hus' martyrdom. The memorial was designed by Ladislav Šaloun and paid for solely by public donations.
Born in 1369, Hus became an influential religious thinker, philosopher, and reformer in Prague. He was a key predecessor to the Protestant movement of the sixteenth century. In his works he criticized religious moral decay of the Catholic Church. Accordingly, the Czech patriot Hus believed that mass should be given in the vernacular, or local language, rather than in Latin. He was inspired by the teachings of John Wycliffe.
