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:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
