The boundary wall

The Roman walls of Aosta are one of the best-preserved ancient city walls in Italy.

Built in 25 BC for the founding of the colony of Augusta Praetoria, they formed a rectangle measuring approximately 724 by 572 metres.
The walls consisted of an inner layer of river pebbles and mortar and an outer layer of travertine blocks.

Sections in which it is still clearly visible: via Hotel des Monnaies, via Carducci, via Carrel (near the bus station), via Monte Solarolo, via Abbé Chanoux. In via Festaz, especially at the junction with via Vevey, you can see the open gaps in the walls for the passage of modern city streets.
