The former fishing village was expanded into a trading port with city fortifications by Pascal Paoli in 1759 during the Corsican Republic in order to have a Corsican port opposite Calvi, which was still Genoese at the time. The late founding of the town is still clearly visible due to the division of the town area into regular street squares. The official language was Italian until 1848.

The region has been inhabited since the 5th to 3rd millennium BC. Around 1000 BC, the town of Agila existed there, which was dependent on the city of Tyros (Phoenicia). The Romans maintained a base called Rubico Rocega at this location during their rule over Corsica until the 4th century AD. After that, the current urban area was almost uninhabited except for a few fishermen and farmers due to its proximity to the coast and the resulting vulnerability to enemy attacks. It was not until the 16th century that residents of the nearby town of Santa-Reparata-di-Balagna opened the first shops near the coast for trade with neighboring communities by sea.

Translation of the explanation board: Erected at an altitude of 1100 meters between the Col de Battaglia and the Col de Croce Dolu, the Peace Sculpture, inaugurated on August 14, 1999, represents mutual aid and solidarity, symbolized by five hands - the five continents - united for peace. Realized from the drawing by Arnaud CASANOVA of the Porticcio school, winner of the Corsican schools competition "1,2,3... it's up to you to play - to draw - to peace". It was made in the Brando Quarry by the sculptors Anne-Marie Moretti, Andros, Dom, Pierre Pardon and Mario Sabaty. From its location we discover the Ghjunsani, the mountains, the Balagne, the sea and the horizon, a symbol of interiority and openness.
