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.
This monument is Aosta's landmark. It was built in 25 BC, the year in which Augusta Praetoria was founded, in honour of Emperor Augustus' victory over the Salassi.
This was once the main entrance to the town. It has two parallel arches 12 metres apart, each with three passages: a central one for vehicles and two side ones for pedestrians.
The cryptoporticus which was part of the Forum complex is a semi-subterranean gallery supported by strong arches.
The impressive 22-metre high southern façade can be seen from the theatre which would have held three or four thousand spectators.
The city walls of Augusta Praetoria reached around 7 metres in height and delineated a rectangle of 724 x 572 metres.
Twenty quadrangular towers stood at the corners of the city walls and all along their perimeter at regular intervals.
This single arch bridge was built at the end of the first century BC over the river Buthier. which changed its course a few centuries after due to a flood.
This villa, built outside the city walls during the Late Roman Republic, includes a residential area with a spa facility and a rustic area.
The necropolis was used both in Roman times and in the Paleochristian period for pagan and Christian burials.
The bold aqueduct bridge of Pondel, 52 metres high, crosses with a single arch the Grand-Eyvia creek in the valley of Cogne.
One of the most beautiful and best-conserved bridges of the Roman world and the biggest with only one span.
Amazing traces of engineering work can be found on the consular road to Gaul: supporting walls, bridges and excavations in the rock.
