San Felice Circeo, a national park headland and holiday homes
Mount Circeo rises alone above the sea at the end of the Pontine plain, and tradition holds that it is the headland of the sorceress Circe in the Odyssey. San Felice Circeo covers its slopes and the surrounding coast, between Sabaudia and Terracina. The headland is part of the Circeo National Park, and in the Guattari cave, on the seaward side, remains of Neanderthals have been found.
The town has a small historic centre on the side of the mountain and, below it, a long band of villas, holiday complexes and houses built from the 1960s onwards, with a marina and beaches. Many homes are lived in only in summer, and the market is mostly second homes. Buyers should know that inside the park and along the coast landscape rules are strict: extensions, swimming pools and changes of use must be checked with the council before signing, and past unauthorised work needs to be looked for.
The resident population is growing all the same. At the end of 2023 Istat, the national statistics office, counted 10,146 residents, up 16.5% since 2011, or 1,437 more people. Foreign residents make up 16.3%. Households are small, 1.95 people on average, and the mean age is 47.3.
Services follow tourism: 103 bars and restaurants, 10.15 per 1,000 residents against 5.54 across the province, while recorded healthcare facilities number just 1. In winter many places close, and for hospitals and offices people go to Terracina or Latina.
Seismic hazard is low: zone 3 on the Civil Protection Department's scale from 1 (highest) to 4, with expected ground acceleration of about 0.060 g. On the coast, beach erosion matters more, and on the headland slope and landslides, which the report reads for the address along with the flood maps. The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps here.

Earthquakes

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.060 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.
