The ancient Desenzano castle was originally built around the year 1000. Enlarged at the end of the 15th century, the castle never became a real military fort, but served primarily as a refuge for the population. The plan of the castle is an irregular rectangle, with the tower that stands out at the entrance on the northern side, protecting the drawbridge, which loopholes for the chains are still preserved. The castle is open to the public.
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.
