Kosava castle is a ruined neo-Gothic castle built in 1830 by Graf Wandalin Puslowski. It is near the palace where Andrzej Tadeusz Bonawentura Kościuszko was born. The architect of the castle was Frantisek Yascholda. The ruined castle is similar to a replica of Tadeusz Kościuszko's house in Merechevschina. After the collapse of the January Uprising in 1863, ownership was transferred to the Trubetskoy family and other Russian aristocrats. During World War I and World War II, the place was severely damaged. Currently, the castle is in the process of restoration.
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.
