Mombaldone, a stone village above the Bormida

In the south of the province of Asti, in Piedmont, where the valley of the Bormida di Spigno narrows between wooded hills, Mombaldone keeps its old stone core on a spur above the river. For the hospital, secondary schools and larger shops the reference is Acqui Terme, further down the Bormida.

The village has an eye on tourism, and it shows in the data: Overture Maps lists 26.04 places to eat per 1,000 residents, against 5.34 in the province. Permanent residents are few: 192 in 2023, down 13.1% on 2011, according to Istat, the national statistics office. The estimated average age is 55.7, against 47.9 in the province, over-65s make up 38.0% and foreign residents 12.5%.

In the old village you will find stone houses built against each other, with thick walls, narrow stairs and often nowhere to park nearby. Outside the old core there are newer houses and farm buildings. In the first case look closely at the roof, the floors and any walls shared with the neighbours; in the second, at the distance from the river and the state of the utilities.

Mombaldone is one of only 4 municipalities in the province of Asti in seismic zone 3 under the Civil Protection classification: all the others are in zone 4. Expected ground acceleration is still low, about 0.050 g, but with old masonry it is worth knowing whether any strengthening work has been done.

The valley floor needs checking for flooding and the slopes for landslides: the report checks the official maps for the address and finds the land parcel on the Revenue Agency's cadastral maps.

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 10 inhabited census areas in Mombaldone. Half of the residents live in areas scoring 52 or more.
