Valgrisenche, the valley of the Beauregard reservoir
Valgrisenche gives its name to one of the side valleys of the Aosta Valley: a long, enclosed valley with the Beauregard reservoir in its upper part and hamlets strung along the stream. The main village lies at around 1,650 metres, and the valley ends against the mountains on the French border.
Buying here means accepting high-mountain living. Winters are long and snowy, and there is a single road down to the main valley, where the larger services are and the road to Aosta. Traditional houses have stone walls and stone-slab roofs; renovation needs builders used to mountain work and permits that respect the landscape. The land is almost entirely natural, with only a minimal share taken up by buildings and roads.
In 2023 there were 186 residents, 12 fewer than in 2011, a fall of 6.1%, according to Istat, the national statistics office. The estimated average age is 49.5, against 47.0 for the Aosta Valley, over-65s make up 28.0% and households average 1.68 people. Foreign residents account for 3.2%. Declared incomes are below the regional average.
Like all 74 municipalities in the Aosta Valley, Valgrisenche is in seismic zone 3 under the Civil Protection classification, with expected ground acceleration of about 0.105 g. For a stone house, the useful checks are the floors, the roof and its snow load.
In an Alpine valley, avalanches, landslides and floods from the stream are assessed for the exact spot. The report reads the official maps for the address and finds the land parcel on the Revenue Agency's cadastral maps, which also cover the Aosta Valley.
