Sperlonga, the white village on its headland and beaches

Sperlonga is a town on the southern Lazio coast, between Terracina and Gaeta, built on a headland that drops sharply to the sea. The old centre, at around 55 metres, is a tangle of alleys, steps and white houses, with long beaches opening on both sides of the headland. Along the shore are the remains of the villa of the emperor Tiberius, with its grotto, and the national archaeological museum that holds its sculptures.

It is a busy seaside resort, and the housing market reflects that: many second homes, summer flats and villas between the coast and the hills behind. Anyone wanting to live here all year will find a much quieter town in winter, with basic services on the spot and the rest in Fondi, which also has the railway station on the Rome-Naples line, or in Terracina. In the old village access is on foot and by steps, something to consider for moving in and for building work.

There were 3,042 residents in 2023, 8.8% fewer than in 2011. The population is older than the provincial average: a mean age of 49.8 against 45.5, with over-65s at 29.2%. Foreign residents are 4.2%, and declared incomes are in line with the average for the province of Latina.

Sperlonga is in seismic zone 3 of the Civil Protection classification, like 29 other municipalities in the province, with an expected ground acceleration of 0.075 g, a low value. By the sea other things matter: salt air on steelwork, render and window frames, damp and the state of terraces. The report checks the official flood and landslide maps for the address and uses the Revenue Agency cadastral data, which are published.

Earthquakes

For Italy's Civil Protection Department, Sperlonga is in seismic zone 3, a zone where strong earthquakes are possible but rare. The region uses a finer breakdown: here the classification is 3B. 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 0.075 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.
