The Castello di Montesegaleis a rural hilltop medieval fortress. It was originally built in the 14th century but over the next centuries was destroyed and rebuilt. An earlier 11th-century tower may have existed at the site.
Documents from 1164 indicate that Emperor Federico Barbarossa conceded a castle or fortress at Montesegale to Pavia. The property was owned by the Count Gambarana by 1311, who became the lord of Montesegale. In 1415, in retribution for a rebellion against Filippo Maria Visconti, his general Carmagnola captured and destroyed the castle. Count Guido Gambarana was captured, tortured, and executed. In 1451, Palatine Count Ottino Gambarana, the son of Guido, obtained from Duke Francesco Sforza restoration of his feudal inheritance. The position of the counts of Montesegale was confirmed by Emperor Charles V in 1525. The property passed on the Giussani family in 19th century, and then to the Jannuzzelli family.
The castle has outer walls and an inner walled keep. The interior walls were restored in 1900 by Agostino Gambarotta. The portal to the inner courtyard has a Latin epigraph that reads Fiat pax in virtute tua et habondantia in turribus tuis ('May there be peace in your strength and prosperity within your towers'). The castle portico has heraldic shields of the Gambarana family.
In 1975, the castle became the site of the local museum of contemporary art.

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.
