Castello di Novi Ligure, Medieval fortress in Novi Ligure, Italy.

Castello di Novi Ligure is a medieval fortress featuring a 30-meter-high square tower surrounded by remaining defensive walls set within a park near the historical center. The structure displays typical elements of Piedmontese military construction and sits in a natural landscape setting.

The castle is first documented in 1153 as a fortified site on the rock protecting a group of houses below that had no walls. The Visconti strengthened it between 1353 and 1392 and again from 1412 to 1447. It passed to Genoa in 1447, was briefly occupied by the Austrians in 1746, and remained Genoese until 1797 before the French dismantled it.

The castle serves as a key stop on the Castelli Aperti circuit, showcasing the defensive heritage of northern Piedmont near the Genoese border. Visitors can experience how this fortification shaped the region's identity.

The grounds are currently undergoing renovation work that includes path improvements and tower restoration. Check current access and viewing conditions before your visit to know what areas are open.

The tower's Ghibelline battlements were lost, but their outline can still be made out beneath the current roof of clay tiles. A 1594 drawing shows the tower crowned with these merlons, and a 1648 drawing adds the castellan's house and troop quarters inside the walls.
