Valderice, from Mount Erice down to the sea at Bonagia

Valderice runs from the slopes of Mount Erice down to the bay of Bonagia, where the old tuna fishery stands. The main town sits at around two hundred and forty metres with Trapani a short drive away, and hamlets and country districts are scattered around it among olive groves, vineyards and small country houses.

Buyers have three kinds of choice. The centre, with houses and low blocks of flats, suits people who work in Trapani and want to stay close to services. The country districts offer detached houses with land, often extended over the years, and it is worth checking that each extension appears in the building permits and the land registry. On the Bonagia coast many homes are second homes used in summer, with the usual problems of salt air and damp.

Istat, the national statistics office, counted 11,395 residents in 2023, down 4.7% since 2011. The estimated average age is 46.8, a little above the province's 46.0, and over-65s make up 25.2%. Foreign residents account for 3.1%. Declared incomes are in line with the province of Trapani. Supermarkets are few per head (0.35 per 1,000 against 0.73), so the big weekly shop often means a drive towards Trapani.

The province remembers the 1968 Belice earthquake and has 6 municipalities in seismic zone 1, the highest. Valderice is in zone 2, but expected ground acceleration in the built-up area is low, about 0.056 g. In older houses what matters most is the state of roofs and floors and the quality of any extensions added over time.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report traces the plot from the address. On the slopes of Mount Erice and along the gullies running to the sea, landslide and flood hazard is checked for the individual address.

For anyone buying in Valderice, 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.
