San Giovanni al Natisone, a river town in the chair district
Between Udine and the border with the province of Gorizia, San Giovanni al Natisone belongs to the so-called chair district, the area around Manzano and Corno di Rosazzo that for decades turned out a large share of Italy's chairs and furniture. The town is named after the Natisone, the river that comes down from Cividale and runs past it; hamlets include Dolegnano and Villanova del Judrio.
Industry is visible. A large part of the land is built on or paved, more than in the farming villages around, and houses, workshops and main roads alternate. Buyers find detached and semi-detached houses, often from the 1970s and 80s, and some traditional Friulian farmhouses with courtyards. Udine is a short drive away and the Udine to Trieste railway stops in town.
Istat, the national statistics office, counted 6,024 residents in 2023, down 1.5% since 2011. Foreign nationals are 12.7%, a high share for Friuli, linked to jobs in local firms. Average age, 47.9, is slightly below the province of Udine (48.5), and over-65s are 26.2% against 27.8%.
In Friuli earthquake risk is very real. San Giovanni is in seismic zone 2 of the Civil Protection Department classification, with expected ground acceleration of about 0.194 g, and the province has 19 municipalities in zone 1, in the hills and mountains to the north. For a house built before modern seismic rules, ask for the design date, the work carried out and the certificates.
Near the Natisone and the Judrio some areas can be affected by floods; the report reads the flood maps for each address. Cadastral maps are published by the Revenue Agency (Agenzia delle Entrate).
