Schloss Leonberg was founded in 1248 by count Ulrich I of Württemberg. The original castle was modified between 1560 and 1565 by the master builder Aberlin Tretsch by order of the duke Christoph. The widow of Frederick I of Württemberg, Duchess Sibylla (1564-1614), used the castle from 1609 as a widow's residence. Later, the castle was still repeatedly used as a residence. The castle today is a tax office.
References: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.
