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.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
