Farra d'Isonzo, vineyards on the plain and the land register
Farra d'Isonzo is a village on the Isonzo plain, between the river Isonzo and the Collio hills, a short distance from Gradisca d'Isonzo and Gorizia. Much of the land is planted with vines, and wineries are as much a part of the landscape as houses. Gorizia, Monfalcone and the motorway are reached by car, and Trieste and Udine are not far.
Buyers should know about one particular feature. Like many municipalities in the former Habsburg lands, Farra uses the tavolare system: property ownership is recorded in the land register (libro fondiario) kept by the land registry office, not in the property registers used in the rest of Italy. Notaries and surveyors know it well, but it helps to know that title searches are done there. The Revenue Agency cadastral maps are still available, and the report traces the parcel from the address.
Istat, the national statistics office, counts 1,675 residents in 2023, down 4.4% from 1,752 in 2011. The average age of 48.8 is close to the 48.0 of the province, with over-65s at 26.7%. Foreign residents are 4.6% and declared incomes are above the provincial average.
Farra is in seismic zone 2 under the Civil Protection classification, like 9 other municipalities in the province of Gorizia, while 15 are in zone 3; the expected ground acceleration is 0.179 g. For a house built before the 1980s, have the floors and roof checked. With the Isonzo nearby, the report also checks the official flood maps for the exact spot.
