Forni di Sotto, the upper Tagliamento and the Friulian Dolomites
In Carnia, the upper valley of the Tagliamento is narrow, wooded and closed in by high mountains. Forni di Sotto occupies a stretch of it, downstream of Forni di Sopra, and its territory lies within the Friulian Dolomites nature park. The village stands at around 780 metres and lives on quiet tourism, hiking and people coming back in summer to the family house.
This is proper mountain country: climate zone F, long cold winters, snow. For a buyer, the heating bill and the state of the roof and windows come before anything else. Many houses were built or rebuilt after the Second World War, and their condition today depends on how well they have been kept up.
Residents have been falling for years: 530 in 2023 against 620 in 2011, a drop of 14.5%. The population is old, with an average age of 52.1 (province of Udine: 48.5) and over-65s at 35.1% against 27.8%. Foreign residents are 6.8%. Declared incomes are below the provincial average.
Earthquakes are a real issue in Friuli. Forni di Sotto is in seismic zone 2 on the Civil Protection department's national scale, like 71 of the 134 municipalities in the province, and the expected ground acceleration in the built-up area is about 0.205 g. Before buying, ask for the year of construction, any structural work and the paperwork for it.
The land registry here is the ordinary one run by the Revenue Agency (Agenzia delle Entrate), with published maps, so the report traces the land parcel from the address. Along the Tagliamento and on steep slopes, flood and landslide hazard is read on the official maps for the exact spot.
