Castello di Annone, in the Tanaro valley between Asti and Alessandria

Castello di Annone lies in the Tanaro valley, on the route between Asti and Alessandria, with its centre at about 110 metres at the foot of a small rise and farmed plain all around. Asti is the nearest provincial capital and the reference for work and services; Alessandria is a short drive away.

It is a lowland village with a straightforward market: village houses with courtyards, detached houses built in recent decades and farmsteads in the countryside, usually at lower prices than in the nearby cities. Declared incomes are below the average for the province of Asti.

There are 1,868 residents (2023), down 3.1% on 2011. The average age is 46.4, lower than 47.9 in the province, and over-65s are 24.7%. Foreign residents are 16.0%.

Earthquake risk is low: seismic zone 4, the lowest class on the Civil Protection scale, with an expected acceleration of 0.044 g. In older houses, the thing to look at is rising damp in the ground-floor walls.

The real issue in the valley is the river. The Tanaro and its tributaries have flood-prone areas marked on the official maps, and for a house on the plain it is worth reading them for the exact address and asking about cellars and basements. The report does this starting from the Revenue Agency (Agenzia delle Entrate) cadastral maps, which are published for Castello di Annone.
