The Visconti Castle in Cusago was built in the 14th century by Bernabò Visconti and used as a hunting lodge by the Visconti family, lords and dukes of Milan. The castle underwent significant changes in the Renaissance period. Today it is in a state of abandonment.
The castle of Cusago had been attended since 1369 by the court of Bernabò Visconti and after his removal from power in 1385 by his nephew Gian Galeazzo. Between 1425 and 1440 the Duke Filippo Maria Visconti devoted great attention to the castle and to the surrounding park. His mistress Agnese del Maino lived occasionally there. In 1438 a little canal (the naviglietto) was excavated to connect the castle to the nearby Naviglio Grande.
During the Ambrosian Republic (1447-1450) part of the buildings were demolished. The function of the castle as a country villa for hunting and parties was restored by Ludovico il Moro. In 1496 he hosted the emperor Maximilian I.
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.
