Castle of Madrignano, Medieval castle in Calice al Cornoviglio, Italy.

The Castle of Madrignano is a ruined defensive building above the village of Madrignano in Calice al Cornoviglio, in the middle and lower Val di Vara, province of La Spezia. At about 400 metres it overlooks the plain of the Vara river to its outlet on the coast. Only parts of the structure remain after its destruction in 1705–1706; the facade was consolidated from 1980 and some rooms have been visitable since 2016.

The castle is first documented in a 1164 imperial diploma of Frederick Barbarossa, which granted the castrum Madrognani to Obizzo Malaspina; it may have been built earlier, perhaps under the Este or the count-bishops of Luni. From 1206 the Malaspina held it until 1416, when the Republic of Genoa stormed and destroyed it. The Fieschi counts followed, then the counts of Mulazzo, and in 1469 the Malaspina recovered it for about three centuries.

The castle has no museum; after a long restoration the site opened to visitors in 2016, and several rooms can be visited. The name Madrignano derives from the castrum Madrognani conceded to Obizzo Malaspina in 1164. The village below, in the Vara valley, keeps the castle as its landmark.

The site reopened to visitors in 2016 after a long restoration, and several rooms can be visited. From the car park below, a short funicular carries visitors up to the castle. Restoration of the whole complex was never completed for lack of funds, so some parts remain unrestored.

The 1705-1706 siege lasted twelve days, not ten, during the War of the Spanish Succession, when Franco-Spanish armies fought the Austrian imperial forces. Damage from that bombardment is still visible in the masonry. The castle was never rebuilt afterwards, only partly adapted, and recovery work begun in 1980 was left unfinished for lack of funds.
