Castelbianco, in the Pennavaire valley behind Albenga

Castelbianco is a village in the hinterland of Albenga, in the Val Pennavaire, a narrow valley between limestone cliffs and woods. The rock faces around the village draw climbers, which brings some life in summer. For schools, shops and services people go down to the Albenga plain and the coast, where the railway and the motorway also run.

Houses are mostly stone, gathered in small clusters on the valley sides, often with terraces and vegetable plots. A buyer should look at access, slope, dry stone walls and rainwater drainage, because on these hillsides the upkeep of the land makes a real difference. Landslide and flood exposure along the stream is checked at the address with the official maps the report consults.

Unlike many inland villages, the population here is holding up: 324 residents in 2023, up 0.9% on 2011. People are younger than in the province of Savona as a whole, with an average age of 47.8 against 49.7 and over-65s at 24.4% against 30.0%. Foreign residents make up 16.0%. Declared incomes remain below the provincial average.

Castelbianco is in seismic zone 3 on the national scale set by the Civil Protection Department, like 46 of the 69 municipalities in the province, and expected ground acceleration in the built-up area is about 0.124 g, a moderate value. In multi-storey stone houses, often built against one another, ask whether work on the roof and floors also took earthquake safety into account.

The Revenue Agency (Agenzia delle Entrate) cadastre is available here and the report goes from the address to the land parcel.
