For example: Via Tempa Tornese 1, Pertosa.

Pertosa, caves on the Tanagro and a village above the valley

The Pertosa-Auletta caves, which you enter by boat along an underground river, are why Pertosa's name is known across Campania. The village stands above the Tanagro valley, at the gateway to the Vallo di Diano, with the A2 motorway running through the valley a short distance away.

Cave tourism shows in the data: bars and restaurants number 9.16 per 1,000 residents, against 6.28 in the province of Salerno. For a buyer, though, the main point is connections: being close to the motorway makes trips towards Salerno and southwards easier, while many services are in the larger towns of the Vallo di Diano.

In 2023 there were 655 residents, down 7.1% on 2011. The average age is 46.6, against 45.2 in the province, and over-65s make up 24.4% of residents, compared with 22.7%. Foreign residents are 4.3%. Average declared income is below the provincial average.

Earthquakes deserve the most attention. The province of Salerno is large and varied: 18 municipalities are in seismic zone 1, 97 in zone 2 and 43 in zone 3. Pertosa is in zone 1, the highest hazard class, with an expected ground acceleration in the built-up area of about 0.213 g. For a masonry house you need the year of construction, any strengthening work with its permits, and an engineer's check.

Between the village on the hillside and the river valley below, other hazards change too: the report reads landslide and flood hazard for the address on the official maps. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the address leads to the land parcel.

For anyone buying in Pertosa, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 7 inhabited census areas in Pertosa. Half of the residents live in areas scoring 60 or more.
