Osterstein Castle is the former castle of the town of Zwickau, today it houses the nursing home.
First mentioned in 1292, it was badly damaged in a fire in 1403, and demolished between 1404 and 1407 under William I, Margrave of Meissen. It was rebuilt during the reign of Christian I, Elector of Saxony in 1587-1590 as a magnificent Renaissance castle.
In the 18th century Zwickau Prison was established in the castle, which with interruptions, was used until after the Second World War. There were numerous prominent prisoners, including Karl May, August Bebel, Rosa Luxemburg and Martin Hoop.
During the Second World War, it was used as a concentration camp. On 31 December 1962, after 187 years, the use of the castle as a prison ended, although a public bathhouse continued to operate in an intermediate wing of modern construction, on the Dr.-Friedrich-Ring. The former arsenal and the cell block were used to house the archives of the local coal mining industry, and for storage by various local businesses. Parts of the premises were demolished.
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.
