Ronchi dei Legionari, the airport town near Monfalcone

Ronchi dei Legionari is home to Friuli Venezia Giulia's airport, the one that serves Trieste, and lies on the Isonzo plain between Monfalcone and the Karst plateau. Its name recalls Gabriele D'Annunzio and his legionaries, who set off from here in 1919 to seize the city of Fiume. Today it is a residential and service town tied to Monfalcone, with its shipyards, and to Gorizia, the provincial capital.

Next to the airport is a transport hub with a station on the Venice to Trieste railway, car parks and buses, and the A4 motorway is a few minutes away. Trieste is about half an hour by train or car. Buyers find detached houses with gardens, semi-detached homes and blocks of flats, with quieter villages on the edge of the Karst. Near the runways, aircraft noise is something to weigh up.

There were 11,833 residents in 2023, almost stable since 2011 (down 1.1%), according to Istat, the national statistics institute. Ronchi ranks 3 in the province of Gorizia by population. The estimated average age is 47.2, slightly below the province, and over-65s are 25.3%. Foreign residents make up 8.4%.

Earthquake hazard is moderate: Ronchi is in seismic zone 3, like 14 other municipalities in the province, while 10 are in zone 2. Expected ground acceleration in the built-up area is about 0.143 g. For houses built before the 1976 Friuli earthquake, check whether any strengthening work has been done.

Property here is registered under the tavolare system inherited from Austrian rule: ownership is recorded in the land book (libro fondiario) kept by the land registry office, not in the property registers used in the rest of Italy. The Revenue Agency's (Agenzia delle Entrate) cadastral maps are still published, so the report finds the parcel from the address. Flood hazard near the Isonzo and the plain's canals is checked for the individual house.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
