Castello di Pomaro Monferrato, Medieval castle in Pomaro Monferrato, Italy.

Castello di Pomaro Monferrato is a fortified structure built on raised terrain in a Piedmont village with heavy walls, towers, and a central courtyard. The layout follows medieval defensive principles and sits amid agricultural fields that define the surrounding landscape.

The Aleramici family began construction in the 12th century, while later ownership by the Paleologi, Gonzaga, and Ardizzone families shaped control of the site. The fortress endured significant damage from military conflict that altered its physical structure.

In the 15th century the Paleologi turned the castle into a residence with a park, used for the summer stays of the marquises of Monferrato. In the 1970s the actress Marisa Allasio, wife of the son of Count Giorgio Carlo Calvi di Bergolo, lived there before moving to Rome. The castle is now also used for ceremonies and events.

The castle is used today for ceremonies and events, so parts of it may be occupied on those days; check before planning a visit. It stands on a hill above Pomaro Monferrato, in the province of Alessandria, and is reached on foot through the village.

Spanish forces destroyed parts of the fortifications in 1637 during European military conflicts, leaving visible marks in the current structure. These wartime damages shaped how the fortress looks today and tell the story of the region's turbulent past.
