Collelongo, the Vallelonga between the Fucino and the national park

Collelongo is the main village of the Vallelonga, the valley that climbs from the Fucino plain towards the mountains of the Abruzzo, Lazio and Molise National Park. This is the Marsica, in inland Abruzzo, at over nine hundred metres, among beech woods and pasture, in a stone village that often sees snow in winter. In January, for the feast of Saint Anthony the Abbot, the village is known for the night of the cottore, large cauldrons cooked in homes and in the streets.

Buying here means choosing the mountains. Houses in the centre are stone-built, on several floors and often in need of updating; newer buildings sit on the edges of the old core. For work, secondary schools and hospital care people drive down to Avezzano. The climate zone is E and winters are long, so heating costs and the quality of the windows should shape what you are willing to pay. Declared incomes are below the provincial average.

The population is falling sharply: 1,070 residents in 2023, 18.5% fewer than in 2011, or 243 people, according to Istat, the national statistics office. The average age is 51.6 against 47.5 in the province, and over-65s are 34.2%, compared with 26.4% provincially. Foreign nationals make up 6.9%.

In the province of L'Aquila, 103 of the 108 municipalities are in seismic zone 1, Collelongo among them, with an expected ground acceleration in the built-up area of 0.244 g, a high value. Before buying a stone house, ask whether it has had seismic strengthening work, with plans and sign-off, and have an engineer look at it.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, and the report works back from the address to the plot. On the valley sides, slope and landslides are checked on the official maps for the exact spot.
