Erice, the hilltop town and the districts joined to Trapani
Erice is really two places, and a buyer needs to keep them apart. On top of the mountain, at more than seven hundred metres, stands the medieval town with its walls, churches and paved lanes, which you can also reach from Trapani by cable car. At the foot of the slope lie Casa Santa and the districts built in recent decades, which run straight into the streets of Trapani. That lower part is where most residents live.
They behave as separate markets. Up on the summit you find old stone houses with narrow access, building work that is often subject to heritage rules, and a cool climate even in summer, with the peak frequently in cloud. Because the town hall sits up there, Erice is classed in climate zone D. Down below there are flats and small detached houses a few minutes from central Trapani, its port and its offices. Average declared incomes are higher than in the rest of the province.
At the end of 2023 Istat, the national statistics office, counted 26,010 residents, down 7.1% on the 28,012 of 2011. The average age is 46.4, slightly above 46.0 for the province, and over-65s make up 25.2%. Foreign nationals are few, 1.7% of residents.
Almost the whole province of Trapani sits in the higher seismic zones set by the Civil Protection Department: 6 municipalities in zone 1 and 18 in zone 2. Erice is in zone 2, yet the ground acceleration expected in the built-up area on the national INGV hazard map is low, about 0.053 g. For a flat in the lower town it is still worth asking when the block was designed and what structural work has been done; for the stone houses on the summit, walls, floors and roofs matter most.
The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for the whole municipality. On the mountainside slope and landslide hazard change from one street to the next, and the report checks them for the exact address.

For anyone buying in Erice, 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 94 inhabited census areas in Erice. Half of the residents live in areas scoring 78 or more.
