Dogna, in the Canal del Ferro along the Fella

The Canal del Ferro is the valley of the river Fella, squeezed between the Julian and Carnic Alps, and it has always been a route between Friuli and Austria. Dogna sits here, just above four hundred metres, where the Val Dogna, a side valley climbing into the Julian Alps, meets the main valley. The valley floor carries the A23 motorway towards Tarvisio, and the old railway line is now the Alpe Adria cycle route, busy in summer.

The municipality is a string of small hamlets along the main valley and up the Val Dogna. The climate is zone F, with long winters and little sun in the cold months at the bottom of such a deep valley. Buyers are usually after a summer mountain house or a base for cycling and walking; to live here all year you need a car and must be willing to drive to larger towns for services and work.

Istat, the national statistics office, counted 150 residents in 2023, 42 fewer than in 2011, a fall of 21.9%. Over-65s make up 40.0% and the average age is 56.1, against 48.5 in the province of Udine. Declared incomes are slightly below the provincial average.

Seismic hazard is high. Dogna is in zone 2 of the national classification, with an expected ground acceleration of about 0.225 g, and the province of Udine has 19 municipalities in zone 1. In Friuli many houses were rebuilt or strengthened after the 1976 earthquake: when buying, ask for the design drawings and the records of structural work.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps. On the valley floor and the slopes, the report checks landslide and river flood hazard on the official maps for the address.
