Trontano, in the Val d'Ossola above Domodossola

Trontano lies in the Val d'Ossola, on the slope rising from the Toce plain towards the mountains, a few kilometres from Domodossola. The municipality has its centre on the hillside, hamlets scattered at different heights and part of its land reaching into the wild valleys of the Val Grande national park. Domodossola is the reference point for work, schools, hospital and trains to Milan and Switzerland.

Buying here means choosing the mountains a short distance from a small town with every service. Houses are stone in the old cores, often with traditional stone-slab roofs, and newer lower down. Sun exposure, winter access, the state of the roof and heating are the things to check, in climate zone E with long winters.

There were 1,648 residents in 2023, down 3.2% since 2011 according to Istat, the national statistics office. The average age of 48.8 and the share of over-65s, 28.3%, are in line with the province of Verbano-Cusio-Ossola. Foreign residents are 3.9%.

Trontano is in seismic zone 3, with an expected ground acceleration in the built-up area of 0.073 g, like 28 of the 74 municipalities in the province. Earthquake risk is limited: in mountain houses, damp, snow load on the roof and the quality of roofing matter more.

The Revenue Agency publishes the cadastral maps. The report finds the land parcel from the address and checks the official landslide and flood maps, to be read carefully on the steep slopes and along the streams running down to the Toce.

For Italy's Civil Protection Department, Trontano 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.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
