The town of Leopoldov was founded in 1664-1669 as a fortress against the Ottoman Turks on the initiative of Emperor Leopold I (hence the name). It was granted town status in 1669. The fortress has served as a state prison since 1855. During the Communist Czechoslovakia, the Communist government used the prison for holding and liquidating political prisoners, particularly in the 1950s. The conditions were harsh for prisoners, and the prison was one of the most notorious in the former Czechoslovakia. Among the inmates was Gustáv Husák (from 1954 to 1960), who would be later communist president of Czechoslovakia. The prison was modernized and reconstructed in the second half of the 20th century. Before 1989 there were approximately 2,600 inmates in the prison. As of 1990, it was the biggest prison in the present-day Slovakia.
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.
