San Leonardo, the Natisone valleys and the Slovene community

San Leonardo is one of the municipalities of the Natisone valleys, in the eastern part of the province of Udine, towards the border with Slovenia. It is made up of small villages scattered across the slopes and along the valley floors, with woods, meadows and chestnut groves; Cividale del Friuli, with schools and services, is a drive down the valley. A Slovene-speaking community lives here, protected by law.

The property market consists of stone village houses, often on two or three floors, villas built in recent decades and a few isolated houses with land. The climate zone is E, and the higher hamlets have cold, damp winters. Average declared income is below the provincial figure.

Istat, the national statistics office, counts 1,019 residents in 2023, 142 fewer than in 2011, a fall of 12.2%. The average age is 50.4 against 48.5 in the province, and over-65s make up 30.7%. Foreign residents account for 6.6%.

Friuli knows earthquakes well, and the classification reflects it: San Leonardo is in seismic zone 2, as are 70 other municipalities in the province, with an expected ground acceleration in the built-up area of 0.247 g. If the house was repaired after the 1976 earthquake, ask for the paperwork on the work done and have an engineer read it.

Revenue Agency (Agenzia delle Entrate) cadastral maps are published, and the report traces the land parcel from the address. For the same spot it shows slope, the official landslide maps and, for houses near the valley-floor streams, the flood maps.
