Treglio, the hills between Lanciano and the trabocchi coast

Treglio sits in the hills of the province of Chieti between Lanciano and the sea, on the stretch of Abruzzo coast known for its trabocchi, old fishing platforms built on stilts. The village is small but close to everything: Lanciano for offices, hospital and schools, the coast for the sea, and the Val di Sangro industrial area for work.

The population is growing: 1,711 residents in 2023, up 8.6% on 2011, according to Istat, the national statistics office. It is younger than the provincial average, with an average age of 44.3 against 47.4 and over-65s at 20.5% against 26.4%. Households have 2.53 members on average and foreign residents are 5.3%. Incomes are above the provincial average.

The market is mostly detached houses, homes with land and small blocks of flats built in recent decades along the hill roads, plus houses in the old village core. On hilly land, look at the slope of the plot, retaining walls and how rainwater drains away.

The province of Chieti has three seismic zones: 22 municipalities in zone 1, 55 in zone 2 and 27 in zone 3. Treglio is in zone 3, with an expected ground acceleration in the built-up area of 0.105 g. For a recent building, ask for the structural design and the year the permit was issued.

The Revenue Agency (Agenzia delle Entrate) cadastral maps are available. The report traces the address back to the land parcel and reads the official landslide and flood maps for that point.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
