Pavone Castle was originally built between the 9th and the 11th century. At the beginning of the 13th century, the castle went to the Romano family and, several years later, Oberto, the new bishop of Ivrea, got it back. In the 14th century, its first and major reconstruction took place. In the 15th century, the castle was abandoned, but, at the end of the century, Bishop Bonifacio Ferrero gave the go-ahead for new reconstruction: building a staircase, enlarging the residential area, and recuperating the external tower.
Wars between Francesco I and Carlo V caused new damage and destruction to the castle, which, following the Napoleonic invasions, was almost completely destroyed.
In 1888, the castle started undergoing renovation works under the direction of architect Alfredo d'Andrade, which were later completed, after his death, by his son Ruy d'Andrade. Several years ago, the castle was turned into a hotel-restaurant and Convention Center.
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.
