Ružica Castle is large ruined castle in Virovitica-Podravina County, Croatia. Since the origin of the medieval structure remains unknown, it has become the stuff of legend over the years. It is one of the most picture-perfect places in the country and a must-see for those in search of hidden gems that are far from mass tourism.
The first document of Ružica castle dates from 1357. It lost its military purpose after Turkish occupation in 1543 and was ruined.
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.
