ROMAN CRYPTOPORTICUS
The cryptoporticus of Aosta was part of the complex of the Roman Forum and is a fascinating underground gallery supported by powerful arches.
In the first century BC, after defeating the local population, the Romans began to colonize this territory: They connected the Alpine passes with the Via delle Gallie road and founded the city of Augusta Praetoria (Aosta). Thus began the five centuries of Roman domination which left monuments and great engineering works in the Aosta Valley.
