Riedheim Castle was built in the 13th and 14th centuries and was owned by the von Randegg family. The castle was allegedly damaged in the Swiss War and around 1500 the residential tower was probably raised and the courtyard portal expanded. In 1518 the castle was owned by Hans von Schellenberg and in 1609 by Konrad Vintler von Plätsch. In 1601 the property went to Archduke Leopold of Austria and in 1735 it was sold to the Petershausen Monastery. In 1803 the castle came to the Margraves of Baden and was sold to the municipality of Riedheim in 1841.
After the tower roof collapsed on May 20, 1951 and the top gable broke off, the top floor was restored in 1957. 1976 to 1978 the castle was restored.
The rectangular castle complex comprises a bering of around 38 by 27 meters with a rectangular residential tower in the middle with late Gothic stepped gables. The four-storey residential tower on an area of approximately 12.35 by 8.7 meters is 27 meters high with the high entrance 4.5 meters high. The wall thickness of the tower shows a thickness of 1.5 meters on the ground floor and a thickness of one meter from a height of three meters.
The curtain wall is around 1.2 meters thick and has scales built on the inside. The arched entrance (around 1550) is on the west side. The castle was surrounded by a moat and probably a rampart. The castle can only be viewed from the outside.
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.
