The municipal area, as well as the capital, is made up of the hamlets of Barco, Corniano, La Fossa, Ghiardo, and Piazzola for a total of 28.02 square kilometers.

Traces of the first human presence (bottoms of huts, ceramic remains, copious siliceous artefacts) in Bibbiano date back to the period between the lower Paleolithic and the Neolithic.

A long Gallic stay is attested by finds from the Iron Age and by the Celtic inflections which remain in the local dialect.

In the 12th century, the history of Bibbiano was inextricably linked to the Canossa family, as the municipal coat of arms demonstrates.

The main reasons are quality forage, stable pastureland, availability of water, and the skill of Bibbiano cheesemakers.
