There is also the D151 road from Pigna in the north-east, passing through the village and continuing south to join the D71 south-east of Cateri.

It flows into the Mediterranean at the east end of Aregno beach, at the edge of the Calcinaiu Natural Site in Corbara.

Evidence that Aregno was already occupied in Roman times has been proven by discoveries of bronze plates from the armies of the emperor Vespasian have been found at the site of San Marcellu.

It has been established that in the 9th century, during the reconquest from the saracens, Roman knights led by the Roman prince Guido Savelli (Count of Balagne since his victory over the Saracens) chose successively the Moorish cities of Corbara (the Castle of Guido was founded in 816), then Sant'Antonino for the capital of the County of Balagna, named after the coastal city which has disappeared.

According to the work of Pierre Savelli de Guido (Count Savelli de Guido, former mayor of Corbara and historian, member of the Archaeological Society of Lorraine), the site is that of the ancient city of Balanea founded by the Phoenicians (?)

It was part of the Balagna region which included at the time the pieves of Tuani, Aregnu, Santo Andrea, Pinu, and Olmia.

The Pieve of Aregnu included the following inhabited places: l'Arpagiola (or Gabiola), la Corbaia, lo Monticello, Santo Antonino, Santa Riparata, Piaza, Pragola, le Torre, Regno, li Catari, lo Lavatogio, Lacona, Spano, Hogio, and Aquapessa.

Without and prior studies of production, processing and marketing, or technical support, this operation was a failure since in 1980 Corsica numbered only 170 hectares of almond trees.
