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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
