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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
