Grignasco, on the Sesia at the mouth of the Valsesia

Grignasco is the last municipality in the province of Novara as you follow the Sesia upstream into the Valsesia: the river runs along the edge of town and here forms the boundary with the province of Vercelli. Behind it are wooded hills and vineyards; to the south, the plain leading to Novara and Borgomanero.

The river is the first thing to consider. Low-lying areas near the Sesia and the streams coming down from the hills should be checked against the official flood maps, and the report does this for each address. The historic centre has old masonry houses, often in need of renovation; newer parts have spread along the main roads and onto the lower slopes.

The population here is older than average: Istat, the national statistics office, counts 4,319 residents in 2023, down 7.9% on 2011, with an average age of 49.8 against 46.7 for the province of Novara and over-65s at 30.2%. Households are small, 2.08 people on average, and foreign residents make up 3.9%. Declared incomes are below the provincial average.

For buyers, a town that is losing people means more homes for sale and more time to choose, but also buildings that need work. Earthquakes are not a major concern: all 87 municipalities in the province are in seismic zone 4, with an expected ground acceleration of around 0.040 g. Look instead at the wiring and heating, the roof, damp in the walls and the energy rating.

Key points

  • On the Novara bank of the Sesia, at the mouth of the Valsesia.
  • Average age 49.8 against 46.7 in the province.
  • 4,319 residents, down 7.9% since 2011.

Overview

Grignasco is a municipality in the province of Novara, in Piemonte. At the end of 2023 it had 4,319 residents, ranked 16 of 87 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Grignasco is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 87 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.040 g, a low value: the level with a 10% probability of being exceeded in 50 years, on rock.

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

Population

Compared with the 2011 census, the resident population has fallen by 7.9%. The estimated average age is 50 years, higher than the province average (47). 30% of residents are over 65 (the regional figure is 27%). Foreign residents make up 3.9% of the population. On average, a household has 2.1 members.

Income and climate

In tax year 2024, taxpayers in Grignasco declared an average taxable income of 25,084 euros, below the provincial average (26,949 euros). The Italian average is 24,895 euros.

Grignasco is in climate zone E, with 2,579 heating degree days: heating may be switched on from 15 October to 15 April, for up to 14 hours a day. The same table puts the town hall at 322 metres above sea level.
