Palazzo San Gervasio, wheat and hills in the Alto Bradano
In the north-eastern corner of Basilicata, where the Lucanian hills give way to wheat fields stretching into Puglia, Palazzo San Gervasio is one of the centres of the Alto Bradano area. The town is known for its art gallery named after Camillo d'Errico, a collection donated to the town by the collector himself, and for an old centre of grand houses and churches.
The economy here is agricultural: durum wheat, vegetables, olive oil. Seasonal workers arrive for the harvests, and foreign residents make up 7.3%. The total population is 4,360, 13.3% fewer than the 5,027 counted in 2011 by Istat, the Italian statistics office, a sharp fall. The average age is 46.5, slightly below the province of Potenza (47.3), and over-65s make up 23.4%. Declared incomes are below the provincial average.
Buyers will find flats and village houses at very low prices, often needing work, and country farmsteads with land. The town hall sits at around 500 metres, in climate zone D, with cold, windy winters: insulation and heating weigh on running costs. The data lists 26 services, 7 of them linked to schools; for hospitals and larger services people look to Venosa, Melfi and Potenza.
Basilicata is seismic: in the province of Potenza, 40 municipalities are in zone 1, the highest in the Civil Protection classification, and 59 in zone 2, Palazzo San Gervasio among them, with an expected ground acceleration of about 0.155 g.

On the clay hills of the area the report measures the slope and reads the official landslide maps for the address. The Revenue Agency's cadastral maps are published.
