Formia, the Gulf of Gaeta and ferries to Ponza
Squeezed between the sea and the Aurunci mountains, Formia stretches along the Gulf of Gaeta on the Appian Way. Ferries leave the port for Ponza and Ventotene, and the station on the Rome-Naples line connects it with both cities. The Romans already built seaside villas here; among the best-known remains is the monument called Cicero's tomb, since the orator had a villa in the area.
The coastal town was largely destroyed during the Second World War and rebuilt afterwards, so many blocks in the centre are post-war. In these buildings the state of the structure, the wiring and plumbing and the service charges matter. Higher up, the villages of Maranola and Castellonorato have stone houses, narrow lanes and views over the gulf, with the usual issues of hill villages: access, parking and repairs.
On the Aurunci slopes and along the streams running down to the sea, landslide and flood hazard should be checked for the address, which the report does using the official maps.
Istat, the national statistics office, counts 36,883 residents in Formia (2023), up 1.5% on 2011. The town is older than the province of Latina, with an average age of 46.9 against 45.5 and over-65s at 25.6% against 22.8%. Foreign residents make up 4.1%. Average incomes are above the provincial average.
Formia is in seismic zone 3 on the Civil Protection scale, like 30 of the 33 municipalities in the province, with an expected ground acceleration of about 0.085 g. The hazard is moderate, but in the rebuilt post-war blocks it is still worth asking for the design date and any surveys. The Revenue Agency publishes the cadastral maps.

Earthquakes
For Italy's Civil Protection Department, Formia is in seismic zone 3, a zone where strong earthquakes are possible but rare. The region uses a finer breakdown: here the classification is 3A. Most municipalities in the province (30 of 33) are in the same zone.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.085 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.
Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.

Liveability area by area
