Castelletto Monferrato, the first hills above Alessandria

Castelletto Monferrato covers the first hills of the Monferrato just outside Alessandria, where the plain begins to rise among vineyards, fields and small woods. Alongside the old core and the farmsteads there are newer areas of small villas and family homes. Alessandria is the reference for work, schools, the hospital and trains.

For buyers the choice is often between a recent villa with garden and garage and a rural house in need of work. With the first, look at the energy rating and running costs; with the second, at the roof, walls and services. The hills are gentle, but on sloping ground drainage matters.

There were 1,423 residents in 2023, 8.7% fewer than the 1,558 of 2011. The average age is 49.6, close to the provincial 48.9, and over-65s make up 27.5%. Foreign residents account for 3.7%. Declared incomes are above the average for the province of Alessandria.

The province of Alessandria has 127 municipalities in seismic zone 3 on the Civil Protection scale and 60 in zone 4. Castelletto is in zone 4, with expected ground acceleration of 0.050 g. The hazard is low, so maintenance and energy savings come first.

The Revenue Agency (Agenzia delle Entrate) cadastral maps cover the municipality and the report finds the land parcel from the address. Landslides on slopes and flooding near watercourses are checked on the official maps for the individual house.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.
