The Visconti Castle in Pavia was built in 1360 by Galeazzo II Visconti, soon after the taking of the city, a free city-state until then. The credited architect is Bartolino da Novara. The castle used to be the main residence of the Visconti family, while the political capital of the state was Milan. North of the castle a wide park was enclosed, also including the Certosa of Pavia, founded 1396 according to a vow of Gian Galeazzo Visconti, meant to be a sort of private chapel of the Visconti dynasty. The Battle of Pavia (1525), climax of the Italian Wars, took place inside the castle park.
There are some significant proofs of the great frescoes showing battles, hunting and middle-class life scenes, which decorated rooms, porches and loggias. Another excellent proof is the complete decoration of the splendid Blue Room with its gold and lapislazuli. Perhaps it was the seat of the Visconti library with its 1.000 manuscripts and commissioned by Petrarch.
It presently houses the Civic Museums of Pavia (Museo Civici di Pavia) including the Pinacoteca Malaspina, Museo Archeologico and Sala Longobarda, Sezioni Medioevale e Rinascimentale Quadreria dell’800 (Collezione Morone), Museo del Risorgimento, Museo Robecchi Bricchetti, and the Cripta di Sant’Eusebio.
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.
