Tellenburg Castle was built around 1200 by the Lords of Kien. After the Lords of Kien, the Lords of Wädenswil became the owners of the castle. They were followed by the Lords of Turn in 1312 and then later by the city of Bern. The original castle was expanded and repaired in the 13th or 14th centuries.
Under Bernese rule, the castle served as the administrative seat of the surrounding area until the creation of the Helvetic Republic in 1798. After 1798 it was used as a poor house. In 1885, the castle was gutted in a fire. It was never rebuilt and has slowly fallen into ruin.
Tellenburg Castle was built as an administrative center and toll station. Telle at beginning of the name likely comes from the German word for toll, Zoll, while burg simply means fortress.
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.
