Donnas, terraced vines and a Roman road in the lower Aosta Valley

At the entrance to the Aosta Valley, along the Dora Baltea river, Donnas is one of the first municipalities you reach coming up from the Canavese area of Piedmont. It is known for the stretch of the Roman road to Gaul cut into the rock, with its arch still standing, and for Donnas wine, a mountain Nebbiolo grown on terraces held up by dry-stone walls.

The valley floor is narrow and holds the village, the railway to Aosta with its station, the main road and, close by, the motorway towards Turin. For anyone working in Ivrea or the Canavese it is a practical base. Up on the slopes there are hamlets and scattered houses, more isolated and with long winters: winter access, gradients and retaining walls need seeing in person.

Istat, the national statistics office, counts 2,391 residents in 2023, down 8.9% on 2011. The average age is 48.2, against 47.0 for the region, and over-65s make up 27.6%. Foreign residents account for 6.6%. Declared incomes are below the regional average.

All 74 municipalities of the Aosta Valley are in seismic zone 3, and in Donnas the expected ground acceleration is 0.050 g. In stone houses, the stone-slab roof, the floors and the insulation deserve more attention than the structure itself.

Revenue Agency (Agenzia delle Entrate) cadastral maps are available. The report reaches the land parcel and, for houses between the river and the slopes, checks the official landslide and flood maps for that single address.
