Saint-Rhémy-en-Bosses, the Great St Bernard valley
The last Italian municipality before Switzerland on the Great St Bernard road is Saint-Rhémy-en-Bosses: high mountain country, with villages at around fifteen hundred metres and the pass higher up. The main road and the tunnel link the valley to the Swiss Valais, but the villages remain small and compact, with stone and timber houses and stone slab roofs. The name is also tied to jambon de Bosses, the local cured ham.
Buying here means choosing real mountain life. Winters are long and snowy, the climate zone is F, and for schools, services and work people drive down to Aosta along the main road. Many houses are second homes for skiing, walking and summer stays. When buying, the roof matters (with the weight of snow and stone slabs it needs careful checking), as do insulation, the type of heating and whether the house can be reached in winter.
Istat, Italy's national statistics office, counted 331 residents in 2023, against 367 in 2011, a fall of 9.8%. The estimated average age is 46.9, practically the same as the 47.0 of the Aosta Valley, and 26.3% of residents are over 65. Foreign residents make up 7.9%. Declared incomes are in line with the regional average.
All 74 municipalities in the Aosta Valley are in seismic zone 3 on the Civil Protection scale; here the expected acceleration is about 0.115 g. With a restored traditional house, ask whether the work also covered walls and floors.
In high mountains natural hazards vary from one point of a slope to another. The report measures slope and elevation for the address and checks the official landslide maps. The Revenue Agency's cadastral maps are published.
