Partanna, olive groves and a rebuilt town in the Belice valley
Partanna stands on a rise in the Belice valley, at around 400 metres, in western Sicily between Castelvetrano and Salemi. Olive groves and vineyards surround it: this is the home of the Nocellara del Belice, an olive for the table and for oil known across the island. In the centre stands the castle of the Grifeo family, who ruled the town for a long time.
What shaped the townscape was the Belice earthquake of January 1968, which hit Partanna and its neighbours hard. Afterwards part of the town was rebuilt, so buildings from different periods now stand next to the older houses that survived. For buyers this is the key point: find out when the building went up, whether it was repaired after the earthquake and what work was done.
Today Partanna is in seismic zone 1, the highest class on the scale of Italy's Civil Protection Department, like 5 other municipalities in the province of Trapani. The expected ground acceleration in the built-up area, from the national geophysics institute INGV, is about 0.135 g. Design documents, structural sign-off and later work should all be requested before signing a preliminary contract.
The town is losing people. At the end of 2023 there were 9,788 residents, down 9.8% on 2011, and the estimated average age of 47.4 is above the provincial 46.0. Over-65s are 27.2%, against 24.7% in the province. This shows in the market: many houses for sale, often inherited, and long selling times. Average incomes are in line with the province.
The climate zone is C, with mild winters. The Revenue Agency publishes cadastral maps for Partanna, and the report uses them to go from the street number to the land parcel, where it also checks landslide hazard on the slopes of the hill.

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 45 inhabited census areas in Partanna. Half of the residents live in areas scoring 60 or more.
