Romans d'Isonzo, the plain between Gorizia and Udine
Romans d'Isonzo is a village on the Friulian plain, west of the river Isonzo, in the province of Gorizia and not far from the boundary with the province of Udine. Until the First World War this part of Friuli belonged to Austria, and the legacy still shows in the land registry and in the layout of the villages, with houses lined up along the streets and inner courtyards. Around it lies flat farmland of arable fields and vineyards.
For newcomers, distances are what matter: Gorizia, Udine, Monfalcone and Trieste can all be reached by car, and the Monfalcone industrial area is within commuting range. The village has the essentials, 3 school sites, 1 pharmacy and 2 supermarkets, while bars and restaurants are few compared with the provincial average.
The population is edging down. Istat, the national statistics office, counted 3,568 residents in 2023, 3.6% fewer than in 2011. The average age is 48.9, against 48.0 for the province, and over-65s make up 27.8%. Foreign residents account for 5.4%, and average declared incomes are in line with the Gorizia area.
The province of Gorizia is split between seismic zones 2 and 3 on the Civil Protection Department scale (the national emergency agency). Romans is in zone 3, but with an expected acceleration of about 0.159 g, high for that class, and Friuli remembers the 1976 earthquake well. For a house built before then, or repaired straight afterwards, ask what structural work has been done.
The land registry here is "tavolare": ownership is recorded in a land book, as under Austria. The Revenue Agency (Agenzia delle Entrate) still publishes the maps, and the report reaches the plot from the address. Near the Isonzo and the plain's watercourses, flood hazard should be checked at the exact spot.
