San Martino d'Agri, a village in inland Basilicata
San Martino d'Agri takes its name from the river Agri, which flows through this part of Basilicata, in southern Italy. The village stands on a hillside at around 660 metres, in a landscape of slopes, woods and fields far from the cities: Potenza, the provincial capital, and the Ionian coast are a long drive away. It is a small municipality where daily life revolves around a handful of basic services.
The most striking figure is the fall in population. In 2023 Istat, the national statistics institute, counted 643 residents, 182 fewer than the 825 of 2011, a drop of 22.1%. Over-65s make up 34.1%, against 25.7% in the province, and the average age is 51.6. Average declared income is below the provincial level.
Buyers, often people returning to a family village or looking for a holiday home, will find masonry houses in the old centre, built side by side and on several levels. Check the condition of the walls shared with neighbouring houses, the roof and any damp, and ask what work has been done over the years.
In the province of Potenza, 40 municipalities are in zone 1 of the Civil Protection (Protezione Civile) classification, the highest class. San Martino d'Agri is in zone 2, with an expected ground acceleration in the village of about 0.215 g. An engineer can tell you whether the house has had seismic upgrading and roughly what it would cost.
The Revenue Agency (Agenzia delle Entrate) cadastral maps are published. On the slopes the report measures the elevation and gradient of the plot and reads the official landslide hazard maps for that address.
