The Visconti Castle of Crenna is linked to the fame of Lodrisio Visconti, who raised against and then reconciled with the members of the family of his cousin Matteo Visconti, Lord of Milan. In the 14th century, the castle underwent expansion and destruction according to the alternative fortunes of Lodrisio.
The Visconti Castle is located on the top of the hill overlooking the Arno valley, open on the opposite side to the plain toward Milan. The location, favoring the control of the territory, is believed to be at the origin of the initial settlements and fortifications.
The castle is mentioned for the first time in 1160. At the end of the 13th century, it was received by Pietro Visconti with other nearby castles (Besnate, Orago and Jerago) as part of a division between him and his nephews Matteo and Uberto, sons of his brother Teobaldo. In the neighbouring Gallarate, Teobaldo, after being captured by members of the opposite faction supporting the Della Torre family, was executed in 1276.
The castle was inherited by Lodrisio, son of Pietro, who greatly expanded it. In the meantime his cousin Matteo became Lord of Milan. After the death of Matteo in 1322, a conflict between Lodrisio and his sons aroused. Lodrisio was dislodged from Crenna and the castle destroyed. After having put together the Compagnia di San Giorgio, a company of mercenaries, in 1339 he was finally defeated in Parabiago by an army led by Azzone, grandson of Matteo. Lodrisio later reconciled with their cousins and the castle was subsequently restored.
The family branch originated by Lodrisio assumed the surname of Visconti di Crenna. Along generations, divisions among brothers lead to the fragmentation of the area surrounding the castle. In the 16th and 17th centuries the building underwent changes and adaptations after further family divisions.
Heavily transformed during the late 19th and the first decades of the 20th century, the area of the ancient castle is today partly surrounded by recent buildings. A tower and other constructions in the form of revival caste are visible from the center of Crenna. The castle can be seen from the distance at the top of the Crenna hill.
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.
