Anzio, the port for Ponza and the landing beaches

Outside Italy, Anzio is still best known for the Allied landing of January 1944, remembered in the war cemeteries of the area. The town is far older than that: it was Antium, a Volscian and then Roman town, birthplace of the emperor Nero, and the ruins of his villa still stand on the headland. Today it lives off the sea, fishing and its port, where ferries and hydrofoils leave for the island of Ponza. To the south it runs straight into Nettuno without a break.

Growth since 2011 has been strong. At the end of 2023 Anzio had 59,633 residents, 9,902 more than in 2011, an increase of 19.9%. Most newcomers are families from Rome looking for lower prices and the sea, which shows in the average age: 45.2 against 46.0 for the province. Foreign residents make up 13.2%. Average incomes are below those of the province of Rome, which the capital pulls upwards.

Buyers should tell apart the centre, close to the harbour and the station, from the residential areas stretching along the coast towards Lavinio. Many of those began as holiday homes and are now lived in all year, so check roads, sewers and utility connections, and whether the property is fully compliant with planning rules. For Rome there is the Rome-Nettuno railway, which stops at Anzio; by car you take the Via Nettunense, which is slow at rush hour.

Seismic hazard is moderate. On the Civil Protection classification Anzio is in zone 3, like 23 other municipalities in the province, while most of them, 97, are in zone 2. Expected ground acceleration is about 0.096 g. By the sea, damp and salt matter more, because they attack steel and concrete: in an older flat, take a close look at balconies and façades.

The land registry is available, and the report locates the plot from the address using the Revenue Agency (Agenzia delle Entrate) maps. Near the ditches running down to the sea and along the higher stretches of coast, landslide and flood hazard should be checked for the individual address.

Earthquakes

For Italy's Civil Protection Department, Anzio 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 0.096 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.

Population

Compared with the 2011 census, the resident population has grown by 19.9%. The estimated average age is 45 years, in line with the province. 22% of residents are over 65 (the regional figure is 23%). Foreign residents make up 13.2% of the population. On average, a household has 2.1 members.

Anzio is in climate zone C, with 1,243 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 3 metres above sea level.

Liveability area by area
