Petrosino, vineyards and a low coast between Marsala and Mazara

Until a few decades ago Petrosino was a rural district of Marsala. Today it is a municipality in its own right, squeezed between Marsala to the north and Mazara del Vallo to the south, with an almost entirely flat territory planted with vines, only a few metres above sea level. Houses are scattered across the countryside and along the low coast facing the Strait of Sicily, rather than gathered in a single centre.

This spread-out layout matters to buyers. Many homes are isolated villas or country houses, often built for the summer and later lived in all year round, and there are plenty of holiday homes along the coast. Before buying, check building permits, any amnesty applications and connections to sewers and mains water carefully, as they cannot be taken for granted here. The railway between Marsala and Mazara crosses the municipality, and both towns are a few minutes' drive away.

There were 7,927 residents in 2023, 2.2% more than in 2011 according to Istat, the national statistics office, which is unusual in this part of Sicily. The estimated average age is 44.0, below the 46.0 of the province of Trapani, with over-65s at 22.3%. Foreign residents account for 9.0%, many of them working on the land. Declared incomes are below the provincial average.

The province of Trapani has municipalities in zones 1, 2 and 4. Petrosino is in seismic zone 2, like 17 others, but the expected ground acceleration in the built-up area, about 0.052 g, is low. In homes near the sea, corrosion of the steel in reinforced concrete and damp matter more, in the mild climate of zone C.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps here, and the report traces the plot from the address. On the low coast and in the dips of the countryside, where water pools after storms, flood risk should be read for the individual address.

For anyone buying in Petrosino, 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.
