Formazza, the Walser valley at the top of Piedmont
At the head of the Val Formazza, on the Swiss border, Formazza lies at the far northern tip of Piedmont. It is split into small hamlets along the floor of the Toce valley, above twelve hundred metres, and keeps its Walser culture: wood and stone houses, German place names and a dialect brought here centuries ago by settlers from the Valais. A little further up the valley is the Toce waterfall, its best-known sight.
This is a place of real winters, in climate zone F, with heavy snow and a road that climbs up the valley from Domodossola. Tourism, hiking in summer and skiing in winter, supports much of the local economy, and many houses are second homes. Buyers should look at insulation, heating, how the roof copes with the weight of snow and whether the house can be reached in the cold months.
In 2023 there were 434 residents, just 1.8% fewer than in 2011. The estimated average age is 51.1, over-65s make up 31.1% and foreign residents 3.5%. Declared incomes are above the average for the province of Verbano-Cusio-Ossola.
Earthquake hazard is low: Formazza is in seismic zone 3 of the national classification kept by the Civil Protection Department, along with 27 other municipalities in the province, and the expected ground acceleration in the built-up area is about 0.081 g. In the mountains, avalanches, landslides and torrent floods matter more, and the report checks them on the official maps for the individual address.
Here too the Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report traces the address back to its land parcel.

Overview
Formazza is a municipality in the province of Verbano-Cusio-Ossola, in Piemonte. At the end of 2023 it had 434 residents, ranked 52 of 74 municipalities in the province.
Earthquakes
For Italy's Civil Protection Department, Formazza is in seismic zone 3, a zone where strong earthquakes are possible but rare. Only 28 of 74 municipalities in the province are in zone 3.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.081 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.
Population
Compared with the 2011 census, the resident population has fallen by 1.8%. The estimated average age is 51 years, higher than the province average (49). 31% of residents are over 65 (the regional figure is 27%). Foreign residents make up 3.5% of the population. On average, a household has 1.9 members.

Liveability area by area
The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 20 inhabited census areas in Formazza. Half of the residents live in areas scoring 60 or more.
