In the first century before Christ, after defeating the native population, the Romans began to urbanise the conquered territory: they organised the land, charted the road networks, connecting the Little and Great Saint Bernard Alpine passes with the Consular road to Gaul and founded the town of Augusta Praetoria (Aosta). This is how the five centuries of Roman rule began in the Aosta Valley.
