Castello Visconteo-Sforzesco

A fortress meant to overawe Novara became a barracks, a prison until 1973 and later a cultural complex. Its brick curtain, the ghirlanda, and four corner towers survive from the Sforza rebuilding.

Why it matters

The castle is Novara's great monument of the Milanese ducal period and a textbook case of Milanese military architecture transplanted to a subject city. Built and rebuilt under the Visconti and then the Sforza dukes of Milan, it was designed less as a residence than as an instrument of control over a contested border town. Under Galeazzo Maria Sforza, between 1466 and 1476, the fortress received its defining element: the ghirlanda, a powerful reinforcing wall with four corner towers and two controlled openings, one towards the countryside and one towards the city, complete with drawbridge and ravelin. That military geometry is still legible on all sides, and the building's later life — prison until 3 January 1973 — adds an unusual modern layer to a medieval shell.

What to notice

The low, massive ghirlanda ring and four squared corner towers show the Sforza approach to artillery-age defence, thick-walled and geometric. Historic entrances on the southern and northern sides retain the fortification's controlled access pattern, including a drawbridge and ravelin toward the city. The courtyard has austere brick arcades and trees. The basement houses the Museo Archeologico di Novara, with Iron Age ceramics and bronzes and Roman glass from the Novarese displayed in vaulted undercrofts.

Context and history

The fortress passed to Francesco Sforza on the death of Duke Filippo Maria Visconti in 1447, and his son Galeazzo Maria Sforza ordered the great strengthening works that produced the ghirlanda and its towers. Under Spanish rule the castle became a node in a wider ring of city fortifications, largely built in the early 1630s, that turned Novara into a stronghold of the Milanese border. Military fashion moved on: in 1788 the eastern bastion was converted into a public walk and the San Giuseppe bulwark into a garden. From 1803 the municipality pressed for the building to become the city prison, and it served that purpose from the late nineteenth century until the inmates were transferred to a new facility, ending the prison function on 3 January 1973. Restoration and cultural conversion followed, bringing exhibitions and museums to the edge of the historic centre.
