Porto Viro, on the Romea road in the Po Delta

Porto Viro takes its name from the Taglio di Porto Viro, the channel the Venetian Republic cut in the early 1600s to push the mouth of the Po further south and keep river silt out of its lagoon. The present municipality was formed by merging the two villages of Contarina and Donada, and it lies right in the delta, in the eastern part of the Polesine area.

The land is all reclaimed plain, partly below sea level, kept dry by embankments and pumping stations. When buying, it matters how far the house is from the embankments of the Po and the drainage canals, and the report checks the official flood hazard maps at the exact address. The Romea main road runs through the municipality towards Chioggia and Venice one way and Ravenna the other, and the sea and the fishing lagoons are close.

With 13,755 residents in 2023, Porto Viro ranks number 3 in the province of Rovigo by population. Since 2011 it has fallen by 6.1%, according to Istat, the national statistics office. The estimated mean age of 48.8 is close to that of a province older than the Veneto average: over-65s are 28.1% in the Polesine against 24.5% for the region, and 27.0% here. Foreign residents are 6.0%, and declared incomes are below the provincial average.

All 50 municipalities in the province are in seismic zone 3 of the Civil Protection classification, and in Porto Viro the expected ground acceleration is about 0.058 g, a low value. On the soft delta soils with a high water table, foundations, cracks and rising damp in the walls matter more, and a survey by an engineer or surveyor before completion is money well spent.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report locates the land parcel from the address.

Key points

  • In the Po Delta, on reclaimed land drained by pumping stations.
  • Population down 6.1% since 2011.
  • Over-65s at 27.0%, in one of the oldest provinces in the Veneto.
  • Seismic zone 3, like the whole Polesine.

Overview

Porto Viro is a municipality in the province of Rovigo, in Veneto. At the end of 2023 it had 13,755 residents, the third most populous in the province.

Earthquakes

For Italy's Civil Protection Department, Porto Viro is in seismic zone 3, a zone where strong earthquakes are possible but rare. All 50 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.058 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 fallen by 6.1%. The estimated average age is 49 years, in line with the province. 27% of residents are over 65 (the regional figure is 24%). Foreign residents make up 6.0% of the population. On average, a household has 2.2 members.

Income and climate

In tax year 2024, taxpayers in Porto Viro declared an average taxable income of 20,711 euros, below the provincial average (23,221 euros). The Italian average is 24,895 euros.

Porto Viro is in climate zone E, with 2,276 heating degree days: heating may be switched on from 15 October to 15 April, for up to 14 hours a day. The same table puts the town hall at 1 metres above sea level.

Services

In the official Ministry of Education and Ministry of Health lists, Porto Viro has 9 schools and 4 pharmacies. The Overture Maps data also lists 7 grocery shops and supermarkets, 13 healthcare facilities, 13 sports facilities and 3 parks and green areas.

There are 0.9 healthcare facilities per 1,000 residents, more than the province average (0.6).

Public transport

We do not yet have open public transport timetables for this municipality: the report says so explicitly, without inventing distances.

How built-up it is

Buildings, roads, car parks and other sealed surfaces cover 6.6% of the land in Porto Viro, compared with 8.4% in the province and 11.9% in the region. In 2024 built-up land grew by 1.5 hectares.

Radon and contaminated sites

Porto Viro is not among the radon priority areas designated by the Regione Veneto in 2025. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Official databases list no open contaminated sites in Porto Viro; 2 have been cleaned up or closed.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Porto Viro: the report checks the address against the ISPRA maps.

House prices

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.

Land registry

The cadastral maps for Porto Viro are public: from the address the report finds the sheet and parcel number.

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 94 inhabited census areas in Porto Viro. Half of the residents live in areas scoring 65 or more.
