Chiavari Castle was built after the convention of perpetual league signed on 1138 between Genoa and Fieschi. The construction started on 1140 and finished probably on 1147. It is one of the first castle erected in the Italian Riviera, over a hill dominating and defending a seafaring village, called Clavai, today Chiavari.
In 1172 the castle was besieged by Opizzone Malaspina, while in 1278 it fell into the hands of Moruello and Alberto Fieschi hands, allied for the conquest of the castle, but just for eight days.
During the first half of the 14th century it was rebuilt several times because of violent battles between the Guelfs and Ghibellines and in that century the village was further fortified by a heavy surrounding wall accessible through seven doors and defended by fourteen towers. Nowadays it is quite easy to see the ruins of the ancient wall of the ancient village of Chiavari.

The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
