Château du Kagenfels (also known as Kaguenfels or Kagenburg) is a ruined castle situated in the Forest of Obernai, in the commune of Ottrott. The castle was constructed in 1262 by Albrecht von Kage, Ministerialis of the Bishop of Strasbourg. The castle passed successively to the nobles of Hohenstein, then to Utenheim and Ramstein, who sold it in 1559 to Lucas Wischbech who repaired and enlarged it. In 1563, the town of Obernai bought it. It was destroyed during the Thirty Years War and is recorded as ruins in 1664.
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.
