Castello Visconteo di Cassino Scanasio, Castle in Cassino Scanasio, Rozzano, Italy

Castello Visconteo di Cassino Scanasio is a fortified complex with four round corner towers surrounding a rectangular inner courtyard. Pointed arch windows and thick brick walls define the structure, located near Milan's outer ring road.

The site is first documented in the 11th century as a fortified rural building called "casinae scanasane"; it is mentioned again in 1239 during the war between Milan and Frederick Barbarossa. The visible structures date to the 14th century. In the early 16th century the Trivulzio family bought the complex and turned it into a country residence, adding the cylindrical towers. It passed to the Pirovano in 1638, then the Della Croce, and in 1836 to the Visconti di Modrone, who made it a farm.

The entrance gateway displays a carved Visconti serpent symbol of the family's authority. This decoration reflects the architectural style that wealthy Milan nobility favored for their fortified country estates.

The castle is located near Milan's outer ring road and is currently not open to visitors. Due to structural safety concerns, it remains closed but can be viewed from the outside.

Cylindrical towers were added only in the 16th century to transform the medieval fortress into a more stately residence. This change shows how the purpose of fortified buildings shifted with the tastes of the nobility.
