Castelmagno, cheese and sanctuary in the Valle Grana

Castelmagno is best known for the protected-origin (DOP) cheese that shares its name, made from the milk of the high pastures of the upper Valle Grana. The municipality is a set of mountain hamlets above a thousand metres, and much higher up stands the sanctuary of San Magno, a destination for pilgrims and summer walkers. This is one of the valleys of Occitan culture in the Cuneo area.

For a buyer, Castelmagno means stone and timber houses in the hamlets, often in need of work, and a life that follows the seasons. In summer walkers and holidaymakers arrive and a few restaurants work flat out; in winter the valley is much quieter and snow slows everything down. The area is in climate zone F, the coldest band in Italy's heating classification. Before buying, check the roof, insulation, winter access and utility connections.

Istat, the national statistics office, counted 55 residents in 2023, 32.9% fewer than in 2011. The share of over-65s (23.6%) is below that of the province of Cuneo (25.1%), while the estimated average age is 50.9 against 46.3. Declared incomes are well below the provincial average.

Castelmagno is in seismic zone 3, together with 140 other municipalities in the province, and expected ground acceleration in the village is about 0.143 g. With stone houses, ask whether the walls and roof have been strengthened.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, and the report gets from the address to the land parcel. At the top of the valley, avalanches, landslides and mountain streams are the hazards to look at first, on the official maps and for the individual house.

Earthquakes

For Italy's Civil Protection Department, Castelmagno 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 (141 of 247) 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.
