Bosco Marengo, the Fraschetta plain and Pope Pius V

Bosco Marengo is a village on the plain around Alessandria, in the area known as the Fraschetta, between Alessandria and Novi Ligure. It is the birthplace of Pope Pius V, who had the large complex of Santa Croce built here, with its church and convent, still the main landmark in the municipality. Around the centre lie farmland and farmsteads.

For buyers the main advantage is location: Alessandria and Novi are close, and from there motorways run to Genoa, Milan and Turin. Homes are mostly detached, with a courtyard or garden, plus some farmhouses to renovate. On the plain, the things to check are rising damp in old walls and insulation, as this is climate zone E with cold winters.

According to Istat, the national statistics office, there were 2,204 residents in 2023, down 12.9% since 2011. The average age is 48.7, in line with 48.9 for the province, and over-65s make up 29.1%. Foreign nationals account for 9.4%. Declared incomes are in line with the Alessandria average.

Bosco Marengo is in seismic zone 3, like 127 of the 187 municipalities in the province, with expected ground acceleration of 0.075 g. The risk is moderate, but for a solid brick farmhouse it is still worth having an engineer look at the walls, especially if you plan new windows or to remove internal walls.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps: the report finds the land parcel from the address and checks the official flood maps for the plain.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
