Świny Castle, formerly a gord, as a stronghold existed in its location already in the 5th century - securing the Lubawecki mountain pass, the site was recorded in Cosmas' documents from 1108, where the gord is recorded as Suini in Poloniae. Possibly, soon after, the gord had been expanded into a military stronghold, at which time it was the seat of the castellans. The castle was mentioned in Pope Adrian IV's Papal bull. After the Bolków Castle was constructed, the castle began to lose its significance, this continued up to the nineteenth century, when the castle suffered severe damage due to hurricanes (1762, 1840, 1848, and 1868). The castle suffered further devastation - it was not until 1931 when the authorities had engaged in securing the castle's ruins. Currently the castle is privately owned.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
