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 stone church of Gamla Uppsala, built over the pagan temple, dates from the early 12th century. Due to fire and renovations, the present church is only a remnant of the original cathedral.
Before the arrival of Christianity in Sweden, Gamla Uppsala was the seat of Swedish kings and a ceremonial site known all over northern Europe. The settlement was home to royal palaces, a royal burial ground, and a great pagan temple. The Uppsala temple, which was described in detail by Adam of Bremen in the 1070s, housed wooden statues of the Norse gods Odin, Thor and Freyr. A golden chain hung across its gables and the inside was richly decorated with gold. The temple had priests, who sacrificed to the gods according to the needs of the people.
The first Christian cathedral was probably built in the 11th century, but finished in the 12th century. The stone building may have been preceded by a wooden church and probably by the large pagan temple.
