The castle in Severin na Kupi is mentioned for the first time in 1558. The Frankopans erected it above the steep bank of the river Kupa, whilst along with the tower the chronicles also mention a wooden castle from the same period. After the death of the last of the Frankopans and the failure of the Zrinski-Frankopan Conspiracy in 1671 this building was also looted and ruined.
The castle gained its current appearance with a renovation in 1803, during the time of Duke Ivan Oršić. It is a two-storey building of a rectangular ground plan, corners reinforced with cylindrical towers and with an interior courtyard and arcade columns. The Chapel of St Florian, located within the castle complex, has small dimensions with an emphasised arched doorway and turret. Alongside the castle is a garden, which is protected and has been declared as a monument of landscape architecture.
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.
