Spigno Monferrato, on the Bormida between Monferrato and Liguria

The branch of the Bormida river that runs through the village is named after it, the Bormida di Spigno, to tell it apart from the river's other branch. This is the Alto Monferrato, the southern end of the province of Alessandria, where the hills turn steeper and more wooded and Liguria is close. The village sits on the valley floor at around 200 metres, with hamlets and farmhouses scattered over the slopes along narrow, winding roads. For secondary schools, the hospital and larger shops, people head down the valley to Acqui Terme.

If you are looking at a farmhouse or an isolated house in the hills, check first how you reach it in winter, where the water comes from and whether it is connected to the mains sewer. The climate zone is E, with cold, damp winters on the valley floor, so heating costs matter.

At the end of 2023 the village had 903 residents, down 19.8% on the 1,126 counted in the 2011 census by Istat, the national statistics institute. The population is old: the estimated average age is 53.9, against 48.9 across the province, and over-65s make up 37.5% (the provincial figure is 28.6%). Households average 1.88 people and foreign residents are 10.5%. Declared incomes are below the provincial average.

The Civil Protection department places the municipality in seismic zone 3, along with 126 other municipalities in the province, and the expected ground acceleration in the village is about 0.050 g, a low value. In old stone houses the weak point is often the roof: the beams, their supports and the way they are tied into the walls deserve a visit from a surveyor or engineer.

Near the Bormida and its side streams, flood hazard changes a great deal from one spot to the next, and so does landslide hazard on the slopes; the report reads both from the official maps for the exact address. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the report can trace an address back to its land parcel.
