Sagone or Saone is a small seaside resort on the west coast of the island of Corsica in the commune of Vico.

[3] The lower valley has large beaches and gentle relief, and is urbanized along its coastal fringe, with an almost continuous constructed line.

Behind the seaside resort there are some remains of the city of Sagone, a Roman colony and later the seat of a bishopric, that was abandoned before the 16th century due to malaria epidemics and barbarian raids.

[4] Residential housing estates have been developed on the side of the Capu a u Bellu, the site of the Genoese tower, somewhat spoiling the landscape.

[5] In 2021 militants of the nationalist Core in Fronte organization denounced the public auction of three sites on the subdivision beside the Genoese Tower.

They noted that the largest and most expensive site was in the immediate vicinity of the tower, and its high price could only be due to speculation that building would be allowed.

[7] After the mausoleum was abandoned it was used to store garbage, and excavators have found ceramics from the Carthage region, coins, pearls, belt buckles and glass lamps.

[4] Pope Paul IV (1555–1559) authorized the Cathedral of Sagone to adopt the Virgin Mary of the Assumption as its patron saint.

[10][11] The building was affected by the frequent absence of the bishops and the wars by the lords of Leca against Genoa and North African incursions, and became dilapidated.

[12] An archaeological park is planned to open in the spring of 2022 including the remains of the cathedral, the tombs, an interpretation center and a green theater.

[22] In the 16th century the Republic of Genoa built many fortresses around the island of Corsica to guard against threats from the Barbary pirates.

In 1566 an embassy sent by Sampiero Corso to the court of Catherine de' Medici was massacred by the Genoese in front of the Tower of Sagone.

[24] After this Napoleon ordered construction of new batteries to make the anchorage safer so as to protect the supply of wood to the Toulon arsenal.

The four companies in Ajaccio, Saint-Florent, Capraïa and Cap-Corse were told to defend this sensitive point in rotation, but only 100 men were present at any time.

Sagone, considered to be one of the eighteen most vulnerable points on the Empire's coast, was to receive 20 guns and to be defended by a line artillery company.
