The castle is linked to Noli’s town walls by a 1.2-kilometer long fortified passage known as the 'muraglia'.
It was a critical defensive point for the independent Maritime Republic of Noli, which existed from 1192 to 1797.
The central circular keep was designed to provide 360-degree surveillance of the Gulf of Noli.
During the 14th century, the castle's defenses were expanded to include advanced parapets specifically designed to resist early gunpowder artillery.
Historical records indicate the castle successfully repelled several sieges by the neighboring Republic of Genoa.
The internal cistern was carved directly into the bedrock to ensure a water supply during prolonged military blockades.
Castello di Monte Ursino is a 12th-century fortification located on the summit of Monte Ursino, overlooking the medieval town of Noli. It served as a strategic defensive bulwark for the Maritime Republic of Noli, controlling trade routes along the Ligurian coast. The structure features a circular keep, double-walled fortifications, and a complex system of defensive battlements. It is connected to the town walls via a long, fortified rampart that descends the hillside. Much of the current masonry dates back to the renovations initiated by the Del Carretto family in the 15th century. Archaeological excavations have revealed layers of occupation predating the medieval castle, including prehistoric and Roman-era remnants. The site is currently managed as a cultural space that hosts exhibitions and public events.
