[2] The village was initially founded by the Ligurian Dectunini tribe, It is speculated that Libarna could be one of the fifteen Oppidums which according to Roman historian Livy surrendered to the consul Q. Minucius Rufus in 191 BC.

Following the barbarian invasions Libarna experienced a period of decline until it was completely abandoned in 452, when the inhabitants joined existing communities or founded new ones, such as Precipiano, Serravalle and Arquata.

[5] Libarna was the autonomous capital of a vast territory which bordered to the east with Velleia, to the south with Genua, to the west with Aquae Statiellae and to the north with Derthona.

[6] Although there is no certain information on the existence of religious buildings in the city, from the votive inscriptions found it is clear that the citizens of Libarna were devoted to Jupiter, Diana and Hercules.

The excavation findings are for the most part preserved in the Turin Museum of Antiquities, where among the most valuable works are mosaic floors, marble statues, bronze busts and figured amber.
