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:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
