Forte di Gavi is a Genoese fortress on a cliff overlooking the village, along the ancient Via Postumia between Piedmont and Liguria. Originally a castle documented in 973, it was transformed between 1626 and 1629 into a six-bastion fortification with a keep and citadel; today it is a museum with courtyards, turrets, prison cells, storerooms and drawbridges. Since 2 February 2026 it has been closed for restoration: check official channels before setting off.

– Keep and citadel: the medieval heart and the lower section with barrack rooms, kitchens and cisterns.

Good to know
Introduction
Forte di Gavi appears suddenly as soon as the road climbs toward the village: a pale stone outline that seems to rise straight from the rocky spur. It has stood there for over a thousand years, guarding the Oltregiogo, between Piedmont and Liguria. It is not a picture-postcard castle or a romantic ruin: it is a true military machine, with six sharp-angled bastions, curtain walls, and gun emplacements that tell of the strategy of the Republic of Genoa. The walls, built from the hill’s limestone, in places merge with the natural rock: you can barely tell where the mountain ends and the fortification begins. From 2 February 2026, the complex is closed for restoration work, so for now there is no interior visit. But climbing up here, walking around the fortress, and letting your gaze sweep over the valleys is still an experience worth the journey.
Historical background
The history of the Fortress begins far back. A notarial deed from 973 is the first evidence of a castle on the rocky outcrop. In 1191 Emperor Henry VI granted it as a fief to the Republic of Genoa, which held it until 1418, when it passed to the Visconti of Milan, then to the Fregoso and Guasco families. In 1528 it returned to Genoa. In 1540 the engineer Giovanni Maria Olgiati began the first radical interventions. After the Franco-Savoyard siege of 1625, between 1626 and 1629 Vincenzo da Fiorenzuola and Bartolomeo Bianco transformed the castle into a bastioned fortress. In 1815 the Congress of Vienna assigned it to the Kingdom of Sardinia; in 1859 it was disarmed and became a prison. During the two world wars it was a prisoner-of-war camp.

Inside the walls: keep, citadel, and six bastions
What you see today is the result of a long transformation. The old medieval castle, with its two trapezoidal towers, was lowered and reduced to a keep (the Altoforte), the core that dominates everything. Around it grew the citadel, the lower section with barracks rooms, kitchens, stables, cells, and cisterns for rainwater. The design by Maculani and Bianco added six bastions – Santa Maria, San Giovanni Evangelista, Mezzaluna, San Bernardo, San Tommaso, and Sant’Antonio – linked by curtain walls with gun ports. The star-shaped plan is regular and recognizable even from afar. In 1673, the fortifications of Monte Moro, the neighboring hill, were added. The garrison could number up to 1,000 men. In some stretches the sandstone rock is carved out, and the walls exceed 20 meters.
Cells, prisoners and stories of escape
For much of its life, the Forte did not defend: it confined. A military prison from the mid-nineteenth century, during the First World War it housed Austro-Hungarian prisoners, then deserters and Allied military personnel in the Second. The cells, storehouses and corridors tell of this second soul, less heroic and more human. Among the best-known stories is that of the British major Jack Pringle, who in 1943 managed to escape with eleven other companions; only he, however, truly got away. Today the museum route passes through courtyards, watchtowers, entrances with drawbridges and educational rooms with wartime artefacts and descriptive panels. It is part of the Castelli Aperti circuit and hosts exhibitions, conferences and historical re-enactments.
Why Visit
The view: from the fortress your gaze sweeps across the hills of Alto Monferrato, the vineyards and the Scrivia valley. Even just for this, the climb is worth it. Military architecture: few places in Piedmont let you read the evolution of a fortification so clearly, from medieval castle to bastioned fortress with its curtain walls and gun ports. The strategic position: you understand at a glance why Genoa cared so much about this outpost in the Oltregiogo, the bulwark facing Milan. Don’t expect a polished museum: here the stone is rough, the spaces wide and the wind blows hard. The village of Gavi, with its narrow streets, completes the visit without needing anything else.
When to Go
There’s no perfect time, but some moments work better. Early morning, when the valley mist is still rising and the pale stone of the Fortress catches the first sunlight, is probably the most evocative time. In autumn the surrounding vineyards turn yellow and red, and the view from above is spectacular. Summer is fine for being outdoors, but it’s best to avoid the middle hours, when the sun beats down on the walls with no shade. Winter, with clear air, offers the best visibility of the mountains. Remember, though, that from 2 February 2026 the Fortress is closed for restoration: for now you can only go up for the village and the view.
In the Surroundings
In the historic centre of Gavi, a visit to the Parish Church of San Giacomo is worthwhile, a masterpiece of Alessandrian Romanesque: a tall tiburio, a façade with high reliefs and a frieze dedicated to Pentecost signed by magister Albertus in the 12th century; the interior has three naves with monolithic columns. All around, the landscape is made up of vineyards from which Cortese di Gavi DOCG is produced: a stop at a local winery is the best way to end the day. The Fort is part of the Castelli Aperti circuit, so you can combine it with other fortresses in the area.

💡 Did You Know…?
In 1943, Major Jack Pringle, an English officer, managed to escape from the fortress with eleven other companions; only he, however, got away for good. Another famous escape involved the officer Alastair Cram. Even earlier, in 1800, the fortress was the only French stronghold in Italy not to surrender to the Austro-Russian forces before Napoleon’s victory at Marengo. Today restoration work continues, and the fortress remains a symbol of the Oltregiogo.
