Torre Viscontea

The Visconti Tower is the sole surviving element of Monza’s medieval walls and castle, built between 1325 and 1357. The quadrilateral tower by the Lambro preserves defensive openings, a Gothic bifora and a stone coat of arms of Charles II of Spain.

Why it matters

The tower is the remaining architectural witness to Monza’s Visconti-era fortifications. Modernisation removed the castle and most of the walls, while this structure survived as a landmark of the city’s defensive and penal history. It served as a prison from its construction until the second half of the eighteenth century.

What to notice

The quadrilateral tower stands along the line of the former castle’s north wall above the Lambro. Its openings include arrow slits associated with a drawbridge arrangement and a Gothic bifora, reflecting different uses over time. A stone coat of arms of Charles II of Spain records a later political presence. The cells known as the Forni were used for prisoners; the tower’s most notable prisoner was Galeazzo Visconti, held here with his brothers and sons for nine months by order of his former ally Ludovico of Bavaria.

Context and history

Galeazzo Visconti and his heirs built Monza’s walls and castle between 1325 and 1357, with the tower anchoring the defensive line by the Lambro. It served as a jail from its construction; the Forni cells remained in use until the second half of the eighteenth century. Urban renewal between 1807 and 1809 demolished the castle and nearly all the walls, sparing the tower, which became a municipal monument.
