Ottobiano, rice fields and farmsteads in Lomellina

In spring, when the rice paddies are flooded, the countryside around Ottobiano turns into a sheet of water divided by low banks. The village is in Lomellina, the plain west of Pavia between the Sesia, the Po and the Ticino, and it is a farming community with a compact centre and large farmsteads spread among the fields.

Homes for sale are mostly two-storey village houses with courtyards, detached houses built in recent decades and the occasional farmstead, often very large and in need of restoration. For work, many people drive to Mortara, Vigevano or Pavia. Two things to know: the water table is close to the surface, so look carefully at cellars and basements, and in summer the mosquitoes from the paddies are a fact of life. Climate zone E means cold, foggy winters. Declared incomes are below the provincial average.

In 2023 there were 1,070 residents, down 9.4% on 2011 according to Istat, the national statistics office. The average age is 48.1, close to the provincial 47.1, and over-65s make up 25.5%. Foreign nationals are 9.3%.

The municipality is in seismic zone 3, like 156 others in the province of Pavia; the remaining 27 are in zone 4. The expected ground acceleration in the built-up area is low, 0.051 g. For a brick farmstead, the points to watch are the roof, the timber floors and rising damp in the walls.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for the municipality, and the report traces the address back to the plot. On a plain criss-crossed by irrigation ditches and canals, the official flood maps are checked for the exact spot where the house stands.
