Saint-Vincent, the casino and spa of the central Aosta Valley
It is called the Riviera of the Alps because the climate is milder than you would expect in the mountains: Saint-Vincent sits on the sunny side of the central Aosta Valley, above the Dora Baltea river, just under 600 metres up, with the Col de Joux behind it. It has a long history as a resort, built around the Fons Salutis thermal spring and the Casino de la Vallée, one of Italy's few casinos.
The valley floor is convenient: the A5 motorway junction and Châtillon-Saint-Vincent station, on the line to Aosta and Turin, are a few minutes away, and Aosta is about twenty kilometres off. For buyers, there are two markets. On one side, flats and village houses for people living here all year; on the other, many second homes and holiday flats, both in the centre and in the higher hamlets. As across the region, French and Italian sit side by side in place names and official documents.
With 4,456 residents Saint-Vincent ranks number 3 in the Aosta Valley by population, but the trend is downward: 4.3% fewer than in 2011. Households are very small, with 1.85 people on average, and the average age of 48.7 is above the regional figure (47.0). Foreign residents make up 9.2%.
Earthquakes are not the main risk: the whole region is in seismic zone 3 of the Civil Protection classification and the expected ground acceleration here is low, about 0.068 g. Slopes and water matter more: landslides, rockfall, avalanches in the higher areas and floods on the Dora and side streams. The report checks the official maps for the individual address. The climate zone is F, so look closely at insulation and the heating system.

Earthquakes
For Italy's Civil Protection Department, Saint-Vincent is in seismic zone 3, a zone where strong earthquakes are possible but rare. All 74 municipalities in the province are in the same zone.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.068 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.
Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.

The estimated average age is 49 years, higher than the province average (47). 27% of residents are over 65 (the regional figure is 25%). Foreign residents make up 9.2% of the population. On average, a household has 1.8 members.
