Gaeta, the headland on the gulf and Serapo beach
On the headland that closes the Gulf of Gaeta, in the south of the Lazio coast, the medieval quarter of Sant'Erasmo climbs towards Monte Orlando, a park above the sea. The rest of the town spread along the bay, facing Formia, and on the open-sea side lies the long Serapo beach. The harbour is home to fishing boats, pleasure craft and a US Navy base.
Tourism shapes the housing market. Many homes are second homes used in summer, especially towards Serapo and on the hills with sea views; in the old quarter houses are often small, on alleys and flights of steps. Gaeta has no working railway station, so for trains you go to Formia on the Rome-Naples line, while the Via Flacca follows the coast to Sperlonga and Terracina.
At the end of 2023 there were 19,300 residents, down 7.0% since 2011 according to Istat, the national statistics office. The population is clearly older than in the province of Latina: an estimated average age of 49.4 against 45.5, over-65s at 29.5% against 22.8%. Households are small, 2.09 people on average, foreign nationals make up 4.3% and declared incomes are above the provincial average.
Earthquake hazard is moderate. In the province, 3 municipalities are in zone 2 and 30 in zone 3 of the Civil Protection Department's classification, Gaeta among them (zone 3), with an expected ground acceleration in the built-up area of about 0.077 g. For houses near the sea, damp, salt corroding the steel in reinforced concrete and the state of facades and balconies often matter more.
The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for Gaeta, so the report finds the land parcel from the address. On the headland and below the rock faces, rockfall should be checked at the exact spot, as should flooding in the low-lying areas by the beach.

Earthquakes
For Italy's Civil Protection Department, Gaeta 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 0.077 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.

Compared with the 2011 census, the resident population has fallen by 7.0%. The estimated average age is 49 years, higher than the province average (46). 30% of residents are over 65 (the regional figure is 23%). Foreign residents make up 4.3% of the population.

Liveability area by area
The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 134 inhabited census areas in Gaeta. Half of the residents live in areas scoring 78 or more.
