Groscavallo, at the head of the Val Grande di Lanzo

Groscavallo closes off the Val Grande, the northernmost of the Lanzo valleys, where the road from Turin climbs to the foot of the Levanne peaks. The municipality is made up of several hamlets along the valley floor and on the slopes, including Pialpetta and Forno Alpi Graie, above a thousand metres. The main village and its hamlets are surrounded by woods, meadows and rock walls.

For decades the valley has been a holiday destination for people from the Turin area, and many houses are second homes. Buyers here need to weigh the distance from services, found further down towards Lanzo, the mountain road in winter and climate zone F, the coldest. In stone houses the roof, insulation and heating are the big items; in flats in holiday apartment blocks, service charges and the state of shared parts.

The population here has grown: 201 residents in 2023, 10 more than the 191 of 2011, a rise of 5.2%. The estimated average age is still high, 52.7 against 47.4 in the metropolitan city of Turin, and over-65s make up 38.3%. Foreign residents account for 3.5%.

Groscavallo is in seismic zone 3, like 271 of the 312 municipalities in the Turin area, with an expected ground acceleration in the village of about 0.104 g. In a narrow Alpine valley, streams and landslides matter too: the report reads the official landslide and flood maps for the address. Revenue Agency cadastral maps are published.

Earthquakes

For Italy's Civil Protection Department, Groscavallo 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.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.104 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.

Compared with the 2011 census, the resident population has grown by 5.2%. The estimated average age is 53 years, higher than the province average (47). 38% of residents are over 65 (the regional figure is 27%). Foreign residents make up 3.5% of the population.
