Trecchina, in the mountains behind Maratea

Trecchina is a mountain village in south-western Basilicata, in the Noce valley, a few kilometres as the crow flies from the Maratea coast. It sits at around 500 metres, high enough for cooler summers than the coast and close enough to reach the sea quickly.

That makes it worth a look if you want a holiday home away from the summer crowds on the shore. The centre has multi-storey stone houses, often in need of updating, while the surrounding rural districts offer detached houses and country homes. Mountain roads need care in winter and slopes are everywhere. Declared incomes are below the average for the province of Potenza.

Istat, the national statistics office, recorded 2,148 residents in 2023, down 7.5% on 2011. The mean age is 49.8, against 47.3 in the province, and over-65s make up 30.4%. Foreign residents account for 3.3%.

Trecchina is in seismic zone 2, with an expected ground acceleration of 0.208 g, and 59 municipalities in the province share that zone. Before buying a stone house in the centre, ask whether structural work has been carried out and whether the permits are on file at the town hall.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps here. The report traces the land parcel from the address and checks elevation, slope and the official landslide maps for that exact spot, details that in the mountains change from one plot to the next.

For anyone buying in Trecchina, 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.
