Montemarzino, a ridge in the Tortona hills

In the hills east of Tortona, where the plain gives way to the first slopes of the Apennines, Montemarzino sits along a ridge of vineyards, fields and patches of woodland. It is a small municipality made up of one main village and scattered farmhouses, and for schools, shops and work people look towards Tortona and the plain along the motorway.

Most homes for sale are rural buildings and village houses in brick or stone, often extended over the years, with courtyards and outbuildings. On a ridge, what matters is the aspect, how rainwater drains away and the condition of any retaining walls. Climate zone E means cold winters that are not especially long, so insulation and the boiler still weigh on running costs.

In 2023 there were 307 residents, down 10.0% on 2011. The estimated average age is 55.4, against 48.9 for the province of Alessandria, and over-65s make up 34.5%. Foreign residents account for 16.9%, according to Istat, the national statistics office. Declared incomes are slightly below the provincial average.

Montemarzino is in seismic zone 3 under the Civil Protection classification, like 127 of the 187 municipalities in the province, with expected ground acceleration of about 0.093 g in the built-up area, a moderate value. With an older house, it is worth asking whether walls and floors were properly tied together during past building work.

The Revenue Agency's cadastral maps cover the municipality, so the report goes from the address to the land parcel and reads the official landslide and flood maps for that plot.
