The Visconti Castle is a castle of Middle Age origin located in Cassano d'Adda. It received the current form in the 14th century, when Bernabò Visconti, lord of Milan, enlarged the existing fortification as part of a defensive system of the Visconti dominions on the Adda river. At the end of the 20th century, after a period of abandonment, it was restored and transformed into a hotel.
A castle in the area is supposed to have existed since the carolingean time. Near the castle, on 27 September 1259, the Battle of Cassano was fought between the two Milanese factions supporting Ezzelino da Romano and Martino Della Torre. The battle ended with the defeat of Ezzelino and the confirmation of the Della Torre family as lords of Milan.
The castle was acquired by the Visconti house after their victory over the Della Torre in the fight for the lordship of Milan. In 1355, it was assigned to Bernabò within the division among him and his brothers Matteo II and Galeazzo II. Between 1355 e 1370, Bernabò, who had received the eastern portion of the Visconti territories, built a defensive line along the Adda river. As part of it, the existing fortification of Cassano d'Adda was strengthened and enlarged.
In the 15th century, Francesco Sforza consolidated the castle with the imposing buttresses, elevated over the Muzza canal, which today characterise the castle.
In the following centuries, lost its military importance, the castle was used for different purposes: warehouse, prison and recovery for homeless people. In the 20th century, restoration works were undertaken, bringing back the castle to its original features. During these works, Middle Age frescos were discovered on the walls and on the vaulted ceilings and accordingly preserved.

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.
