Nus, the Dora Baltea and the Saint-Barthélemy valley

Nus is one of the municipalities of the central Aosta Valley, on the northern side of the Dora Baltea river, east of Aosta. The village sits on the valley floor at around 530 metres, crossed by the main road and the railway, with the motorway running through the valley. From here a road climbs into the Saint-Barthélemy side valley, through pastures and woods, up to the regional astronomical observatory.

Being close to Aosta matters a lot: many residents work in the city or on the plain and choose Nus for a larger home. On the valley floor there are small blocks and detached houses, while the villages on the slopes have stone and timber houses, often restored, and some second homes for summer and skiing. Above the village you can see the remains of the Pilato castle and the castle of Nus.

Istat, the national statistics office, counted 2,950 residents in 2023, up 0.2% since 2011, so the population is stable. The average age of 45.1 is below the regional 47.0, with over-65s at 21.3% and foreign nationals at 4.5%. Average incomes are slightly below the regional figure.

The municipality is in seismic zone 3, with an expected ground acceleration of 0.078 g. The climate zone is F, the coldest: insulation, windows and the heating system weigh on the choice and on yearly running costs. In the mountains, location matters. The report checks elevation, gradient and the official landslide and flood maps for the address, because conditions differ between the valley floor and the higher villages.
