Nettuno, a walled seafront village with trains to Rome

Nettuno lies on the Lazio coast south of Rome, just past Anzio, with which it forms one continuous town facing the Tyrrhenian Sea. Its medieval village is enclosed by walls on the seafront, not far from the Forte Sangallo, and the sanctuary of Santa Maria Goretti stands on the promenade. Outside the centre is the American military cemetery linked to the Anzio landings of 1944.

Many residents work in Rome. The simplest way in is the Rome to Nettuno regional train, which ends at the station in the centre; by car you take the Nettunense road, often congested at rush hour. Anyone thinking of moving here should try the journey on a weekday.

The market mixes year-round homes with summer houses, especially in the coastal areas east of the centre. A stretch of coast is taken up by a military zone. Near the sea, check the condition of façades, balconies and the steel in reinforced concrete, which salt air wears down quickly.

According to Istat, the national statistics office, there were 48,237 residents in 2023, up 6.1% since 2011. The average age of 46.2 is in line with the province, and foreign residents make up 9.9%. Average declared incomes are well below those of the province of Rome, though the capital pulls that figure up. There are 282 bars and restaurants, 5.85 per 1,000 residents, above the provincial average.

Seismic hazard is moderate. Nettuno is in zone 3 on the Civil Protection Department's scale, like 23 other municipalities in the province, while most of the province, 97 municipalities, is in zone 2. The expected acceleration is about 0.092 g. The Revenue Agency publishes the land registry maps, and the report finds the plot from the address along with flood and landslide data for that spot.

Key points

  • Walled seafront village and a direct regional train to Rome.
  • 48,237 residents, up 6.1% since 2011.

Overview

Nettuno is a municipality in the province of Roma, in Lazio. At the end of 2023 it had 48,237 residents, among the most populous in the province (10 of 121).

Earthquakes

For Italy's Civil Protection Department, Nettuno 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. Only 24 of 121 municipalities in the province are in zone 3.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.092 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 grown by 6.1%. The estimated average age is 46 years, in line with the province. 23% of residents are over 65 (the regional figure is 23%). Foreign residents make up 9.9% of the population. On average, a household has 2.2 members.

Nettuno is in climate zone C, with 1,255 heating degree days: heating may be switched on from 15 November to 31 March, for up to 10 hours a day. The same table puts the town hall at 11 metres above sea level.

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.
