Historic documents attest to the fact that Frinco was an established community as far back as 1100-1200. With a castle as of the tenth century, under the jurisdiction of the Church and Commune of Asti, it was held by a succession of powerful Asti families: Pelletta, Turco, Mazzetti, Conti di Camerana, a branch of the Roeros of Settime. It was later bought by the Oblati Giuseppini of Asti as a Seminary for Novices, then sold off to private individuals.
In 1487 the Mazzetti family were granted the privelege of minting their own gold and silver coins.

The commune covers an area of around 7.28 sq km, crossed by a busy main road with good public transport connections to Asti. As well as the village, where the town hall lies, there are a number of hamlets: Bricco Morra and Rampone, Gavelli, Molinasso, San Defendente, and Valmarchese. The main activities are agriculture and trade.

Apart from the Castle, which was requisitioned during the First World War to house Austro-Hungarian prisoners, there is the town hall, the monument to fallen soldiers, the Memorial Park, the church, the Graziano building, various chapels scattered throughout the hills and plaques commemorating historical events, such as that of Bricco Marina, which records the visit of King Vittorio Emanuele III, who came here on 28 August 1928 to coordinate military operations.
