Rocca di Orino lies on a rocky spur. The first record dates from 1176, however some fortifications were there already in the Roman ages. The castle was a military stronghold in the struggles between the Guelphs and Ghibellines during the thirteenth century until the victory of the Ghibellines. After the Duchy of Milan was created, the castle lost its purpose. It gradually fell into disrepair.
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.
