Triora, the village of the upper Argentina valley

Triora is known for the witch trials of the late sixteenth century, remembered today by a museum and many reminders around the village. Beyond the reputation, it is a mountain village in the upper Argentina valley, at around 780 metres, with stone houses packed close together, covered alleys and a large territory rising towards the Ligurian Alps. Taggia, on the coast, and Sanremo are the reference towns for work and services.

The population here has grown: in 2023 there were 400 residents, up 7.0% on the 374 of 2011. Foreign residents account for 26.8%, a share that shows how much the village draws people from elsewhere. The estimated average age is 50.0 (provincial figure 48.7) and over-65s make up 30.8%.

Village houses are often on several levels, with steep stairs, thick walls and access on foot only: they appeal to people looking for a home with character, but need checks on the roof, damp, services and how building materials would be carried in for any work. In climate zone F winters are cold and heating needs careful thought.

Triora is in seismic zone 3 of the national classification kept by the Civil Protection Department, like 35 other municipalities in the province of Imperia, and the expected ground acceleration in the built-up area is about 0.159 g. In a village of adjoining buildings, structural work on one house also depends on its neighbours: ask whether any work was carried out jointly.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps and the report finds the land parcel from the address. On the steep valley slopes, landslides and rockfall are checked on the official maps for the individual plot.

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

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 13 inhabited census areas in Triora. Half of the residents live in areas scoring 64 or more.
