Aosta is a city where the Alps seem to lean close enough to hear the traffic of the old Roman road. The mountains form a dramatic frame, but the most revealing journey is on foot through the centre: an arch, a gate, fragments of walls, a theatre façade, then the softer scale of medieval churches and cloisters. Aosta is not a ruin field set apart from modern life. The Roman plan still guides daily streets, and the city’s later history sits directly on top of it.
The Romans founded Augusta Praetoria in 25 BC after the defeat of the Salassi, in a strategic valley connected to routes over the Great and Little St Bernard passes. The settlement was laid out in the disciplined rectangle of a military camp, with the north–south Cardo and east–west Decumanus meeting at its centre. The grid remains legible in the modern street pattern. Aosta’s name carries that imperial foundation forward, while local heritage sources also preserve the memory of the people whose territory Rome conquered.
