Vizmburk Castle was founded by Tas or Peter of Skalice and it was mentioned first time in 1279. This noble house with the stirrup in their coat of arms was known already in the 12th century, when their members held the burgrave office in Kladsko. The Vizmburk estate was a fairly large one with the economic centre in the town of Úpice.
In 1330 the the lords of Dubá owned the estate. Jiří of Dubá supported the Hussites movement which resulted in frequent raids of his estate by Silesian troops. The princes and burghers of Silesia and Lusatia eventually sealed the faith of the Vizmburk castle. Instead of arms they used the power of money. In 1447 the castle was bought up and intentionally demolished.
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.
