Cosseria, Val Bormida and the castle of the 1796 battle

In April 1796, on the ruins of Cosseria castle, a small Austrian and Piedmontese garrison held out against the assaults of Napoleon's army before surrendering, during his first Italian campaign. Today those ruins look over a scattered municipality in Val Bormida, the hinterland of Savona beyond the watershed, towards Piedmont: wooded hills, meadows, small hamlets and isolated houses.

Val Bormida has a different climate from the coast. This is climate zone E, with cold winters, fog and sometimes snow, so heating has to be budgeted for. Jobs are in the valley's businesses and in Savona, reached by car down towards the sea. Homes for sale are mainly detached houses with a garden or land, some of them rural buildings needing work. Declared incomes are in line with the provincial average.

In 2023 there were 1,037 residents, 4.0% fewer than in 2011. The average age is 48.9 against 49.7 for the province, and over-65s make up 27.6%, fewer than the provincial 30.0%. Foreign nationals account for 5.3%.

In seismic terms the province of Savona is split: Cosseria is one of the 19 municipalities in zone 4, the lowest class, while 46 are in zone 3 and 4 in zone 2. The expected ground acceleration is 0.057 g. In a country house, the roof, walls and systems matter more.

The report uses the Revenue Agency (Agenzia delle Entrate) cadastral maps to trace the address to its land parcel, useful in a municipality of scattered houses where boundaries and access are not always obvious. Between the slopes and the streams of the Bormida, landslide and flood hazard are checked on the official maps for the exact spot.

Key points

  • Scattered municipality in Val Bormida, inland from Savona.
  • Seismic zone 4, the lowest class, acceleration 0.057 g.
  • Population down 4.0% since 2011.
  • Inland climate: cold winters, unlike the coast.

Overview

Cosseria is a municipality in the province of Savona, in Liguria. At the end of 2023 it had 1,037 residents, ranked 39 of 69 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Cosseria is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Only 19 of 69 municipalities in the province are in zone 4.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.057 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.

Population

Compared with the 2011 census, the resident population has fallen by 4.0%. The estimated average age is 49 years, in line with the province. 28% of residents are over 65 (the regional figure is 29%). Foreign residents make up 5.3% of the population. On average, a household has 2.1 members.

Income and climate

In tax year 2024, taxpayers in Cosseria declared an average taxable income of 24,094 euros, in line with the province (24,469 euros). The Italian average is 24,895 euros.

Cosseria is in climate zone E, with 2,519 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 516 metres above sea level.

Services

The data shows no grocery shops and supermarkets within the municipality, against a provincial average of 1.0 per 1,000 residents.

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 7.4% of the land in Cosseria, compared with 6.7% in the province and 7.3% in the region. In 2024 built-up land stayed almost the same.

Radon and contaminated sites

Cosseria is not among the radon priority areas designated by the Regione Liguria in 2026. According to the ISPRA map, the estimated radon emission in the municipality is low. 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 contaminated sites in Cosseria.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Cosseria: 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 Cosseria 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 29 inhabited census areas in Cosseria. Half of the residents live in areas scoring 52 or more.
