Casanova Lerrone, hamlets of the Val Lerrone above Albenga
Inland from Albenga on the western Ligurian coast, the Val Lerrone climbs from the plain towards the hills and mountains, and Casanova Lerrone takes up much of it with its main village and a string of hamlets on the slopes. The landscape is typical of inland Liguria: terraces, woods, stone houses grouped in small clusters and roads that bend with the valley. The coast, with Albenga and its services, is within easy driving distance.
Foreign residents make up 15.0% of the population. Istat, the national statistics office, counted 740 residents in 2023, practically the same as in 2011 (down 0.5%). The average age is 51.1, against 49.7 in the province of Savona, and over-65s make up 32.6% against 30.0%. Average declared income is below the provincial figure.
Buyers will find stone houses in the historic hamlets and rural buildings with land, often in need of restoration. Car access, the upkeep of dry-stone walls and terraces, water supply and utility connections all matter. This is climate zone D, with mild winters.
Earthquakes need to be considered. Casanova Lerrone is in seismic zone 3, like 45 other municipalities in the province, but the expected ground acceleration in the village is about 0.145 g, not a negligible value. For a stone house, ask whether the roof and floors have been rebuilt and whether any strengthening work has been done.
The Revenue Agency (Agenzia delle Entrate) cadastral maps cover the municipality. The report finds the land parcel from the address and checks landslides and flooding on the official maps, worth looking at both on the slopes and near the stream.
