Stregna, scattered hamlets in the Natisone valleys

Stregna is a municipality in the Natisone valleys, the hill and mountain belt between Cividale del Friuli and the border with Slovenia. Its territory is split into many small hamlets scattered over the slopes among woods and meadows, with the town hall at about four hundred metres. Local varieties of Slovene have long been spoken here alongside Italian, as the place names show. People go down to San Pietro al Natisone and Cividale for services and work, and Udine is within driving distance.

Houses are mostly stone, often in clusters of a few homes, on narrow, sloping roads. Buyers should check year-round car access, retaining walls and the roof. Climate zone F means long winters, so insulation and heating weigh heavily on costs.

Earthquakes need careful thought. Stregna is in seismic zone 2, like 71 of the 134 municipalities in the province of Udine, and expected ground acceleration is about 0.243 g. Friuli has long experience of rebuilding after earthquakes, so for a masonry house ask what structural work has been done and with which permits.

In 2023 there were 284 residents, 114 fewer than the 398 of 2011, a fall of 28.6%. The estimated average age is 55.9, against 48.5 in the province, and over-65s make up 40.1%. Foreign residents account for 5.3%. Declared incomes are below the provincial average.

Revenue Agency cadastral maps are published for Stregna, and the report links the address to the land parcel.
