Chiusa di San Michele, at the mouth of the Susa valley
Chiusa di San Michele takes its name from the old chiuse, the fortifications that once blocked the Susa valley where it narrows between Monte Pirchiriano, crowned by the Sacra di San Michele abbey, and the opposite slope. Today it is a valley floor village at the entrance to the valley, crossed by the main road and close to the railway and the motorway to the Fréjus tunnel. Turin is about half an hour away by car.
Its position suits people who work in the city or lower down the valley. The market offers houses in the old core, flats and more recent villas, in a compact settlement on flat ground. In a block of flats from the 1970s or 1980s, look at the service charges, the energy rating and the condition of the facades and roof.
Istat, the national statistics office, counted 1,516 residents in 2023, down 10.3% since 2011. The average age of 47.3 almost matches the 47.4 of the province of Turin, and over-65s make up 25.2%. Foreign residents account for 9.0%. Declared incomes are below the provincial average.
Earthquake hazard is moderate: Chiusa is in seismic zone 3, like 271 of the 312 municipalities in the province, with an expected ground acceleration of about 0.122 g. For a building that has been extended or raised, ask for the permits and the design of the new parts.
The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps and the report reaches the land parcel from the address. Near the Dora and the streams coming down the slopes, flood hazard is read for the exact spot.

Earthquakes
For Italy's Civil Protection Department, Chiusa di San Michele is in seismic zone 3, a zone where strong earthquakes are possible but rare. The region uses a finer breakdown: here the classification is 3S. Most municipalities in the province (271 of 312) are in the same zone.

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