Sutrio, in Carnia at the foot of the Zoncolan

In Carnia's But valley, Sutrio lies on the side from which one of the roads up Monte Zoncolan climbs, a mountain known for its Giro d'Italia stages and its ski slopes. Tolmezzo, down the valley, is the reference town for schools, hospital and offices; Udine is further away, reached by heading down to the Friuli plain.

The village has a core of stone houses with wooden balconies and steep roofs, typical of Carnia, surrounded by homes built or rebuilt in recent decades. Alongside residents, some people buy a house here for winter or summer in the mountains. The climate is cold (climate zone F), so insulation and the heating system are the first things to check.

In 2023 there were 1,225 residents, down 10.6% since 2011 according to Istat, the national statistics office. The average age is 48.2, in line with 48.5 for the province of Udine, and over-65s make up 28.6%. Foreign nationals are few, at 1.4%.

Sutrio is in seismic zone 2, like 70 other municipalities in the province, and the expected ground acceleration in the built-up area is about 0.188 g. In Friuli many houses were repaired or rebuilt after the 1976 earthquake, so ask when and how the work was done and whether there has been more recent work.

The land registry is published by the Revenue Agency (Agenzia delle Entrate), and the report finds the land parcel starting from the address. In an Alpine valley, between the But torrent and the slopes, the report checks the official maps for flooding, landslides and avalanches at the exact location.

For anyone buying in Sutrio, 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.
