Calatafimi-Segesta, a hill town and a Greek temple
One municipality, two names. Calatafimi is the town, built on a rise in the hills inland from Trapani in western Sicily; Segesta is the archaeological site within its boundaries, with the Doric temple and the theatre on Monte Barbaro. In 1860 Garibaldi fought his first battle in Sicily here, and the ossuary at Pianto Romano commemorates it.
Tourism apart, Calatafimi is a farming town of vineyards, olive groves and wheat between Alcamo and Trapani, with the gulf of Castellammare to the north. The Palermo to Trapani motorway runs close to the temple, and both Trapani and Palermo airports are within driving distance. The old town is on a slope, and many stone houses stand empty or need renovation: the population has been shrinking for years and plenty of property is on the market.
Istat, the national statistics office, counted 6,066 residents in 2023, 872 fewer than in 2011, a fall of 12.6%. Average age is 48.2 against 46.0 in the province, and 28.7% of residents are over 65, compared with 24.7% across the province. Foreign nationals are 2.1%, and incomes are a little below the local average.
Calatafimi is in seismic zone 2 of the Civil Protection Department classification, with expected ground acceleration in the town of about 0.102 g. The province also has 6 municipalities in zone 1, in the Belice valley, where the 1968 earthquake shaped a whole generation of building. If you buy a stone house, ask what structural work has been done, under which permits, and have floors and roof inspected.
On the clay hills inland, slow-moving landslides are not unusual, and each slope around the town is different: the report checks the official hazard maps for the address. Cadastral maps from the Revenue Agency (Agenzia delle Entrate) are published.
