Castel di Sangro, the Alto Sangro's main town near the ski slopes
Castel di Sangro is the largest town in the Alto Sangro, the upper valley of the Sangro river, downstream of the Abruzzo National Park and close to the border with Molise. It lies at around eight hundred metres, with the old town climbing the hill and the newer part spread across the valley floor, and it serves the villages around it: offices, schools and shops are here.
The ski slopes of Roccaraso and Rivisondoli are a few kilometres away, and that shapes the housing market. Alongside year-round residents there are many flats used in winter and let out during the snow season. There are 65 cafés and restaurants, far more per head than the provincial average. The SS17 road links the town with Sulmona and Isernia, and the old railway from Sulmona now carries heritage trains for tourists. The painter Teofilo Patini was born here.
It is one of the few mountain towns that is growing. Istat, the national statistics office, counted 6,598 residents in 2023, 10.2% more than in 2011. Households are very small, 1.93 people on average, which points to many people living alone. The average age is 46.9, against 47.5 for the province of L'Aquila, and foreign residents make up 6.4%. Declared incomes are below the provincial average.
Earthquakes are the main issue. In the province of L'Aquila, 103 of the 108 municipalities are in seismic zone 1, the highest on the Civil Protection Department's scale, and Castel di Sangro is one of them, with an expected ground acceleration of about 0.265 g in the built-up area. Before buying a flat in a 1970s block or a stone house in the old town, ask for the structural paperwork and, if you can, have a surveyor look at the building.
The climate matters too: long winters with snow and frost make insulation and heating important. Along the Sangro and on the hillside, the report reads flood and landslide hazard for the exact address. The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps here, so each address can be traced to its land parcel.
