Savogna d'Isonzo, between the Isonzo and the Gorizia Karst
Savogna d'Isonzo, Sovodnje ob Soči in Slovene, is a bilingual municipality on the edge of Gorizia, where the Isonzo plain meets the first heights of the Karst. A Slovene-speaking community lives here, with its own schools and associations. On the heights are First World War sites linked to Monte San Michele.
Gorizia is a few minutes away, and people working there or across the border in Slovenia find detached houses with gardens, rural homes in the hamlets and villas built in recent decades. On the plain, proximity to the river matters; on the heights, the Karst rock and exposure to the bora, the strong north-east wind.
Istat, the national statistics office, counts 1,707 residents in 2023, down 1.2% on 2011. The average age is 48.8 against 48.0 in the province, over-65s are 27.5% and foreign residents 7.1%. Incomes are in line with the provincial average.
Savogna is in seismic zone 2, like 10 municipalities in the province of Gorizia; the other 15 are in zone 3. The expected ground acceleration in the built-up area is 0.181 g. With a house built before modern seismic standards, ask what work has been done on walls and floors.
One thing worth knowing: the tavolare land book system applies here too, inherited from Austrian rule, and ownership is checked in the land book (Libro fondiario). The Revenue Agency (Agenzia delle Entrate) cadastral maps are published all the same, so the report traces the address to the plot and checks the official flood and landslide maps for that point.
