Santa Maria Maggiore, the heart of the Vigezzo valley
In the Valle Vigezzo, which climbs from Domodossola towards the Swiss border, Santa Maria Maggiore is the main village: it has shops, schools and a station on the Vigezzina, the narrow-gauge railway between Domodossola and Locarno. The village sits on a wide upland basin at around eight hundred metres and is also known for its chimney sweep museum, a trade that for centuries took people from the valley to work abroad.
Buying here means choosing a proper mountain place. It is in climate zone F, the coldest: snow is normal in winter and heating is a major cost, so insulation, boiler and windows deserve a careful look. The market mixes traditional stone houses with slate roofs, chalets and flats in small blocks.
The population is holding up, which is not a given in the mountains: 1,303 residents in 2023, up 3.1% on 2011 according to Istat, the national statistics office. The average age is 48.0, slightly below the 49.0 of the Verbano-Cusio-Ossola province, and over-65s are 26.4%. Foreign residents are 5.2%.
The province has two seismic classes: 28 municipalities in zone 3 and 46 in zone 4. Santa Maria Maggiore is in zone 3, with a low expected ground acceleration of 0.060 g. Snow load on the roof and the state of the walls matter more here than earthquakes.
Cadastral maps from the Revenue Agency (Agenzia delle Entrate) are available. In an Alpine valley, streams and slopes deserve attention: the report checks the official landslide and flood maps for the exact address.
