Grosseto, the heart of the Maremma
Grosseto is the main town of the Tuscan Maremma: a lowland city on the river Ombrone, a few kilometres from the Tyrrhenian Sea, which grew mostly after the marshes around it were drained. Its old core is still enclosed by the hexagonal Medici walls, and the municipal area reaches the coast at the seaside village of Marina di Grosseto.
Among Tuscany's provincial capitals, Grosseto has one of the lowest seismic classifications: zone 4, the lowest of Italy's four classes. Its province is mixed, with 10 municipalities in zone 4, 16 in zone 3 and 2 in zone 2. Expected ground acceleration in the built-up area is about 0.065 g, moderate but close to the low band. Zone 4 does not mean ignoring the issue entirely: for an older building, the state of the structure is still worth asking about.
The population is growing. At the end of 2023 there were 81,482 residents, 3.6% more than in 2011, which is 37.8% of the entire province. The town is also younger than the area around it: an estimated average age of 47.6 against 49.1 for the province, with over-65s at 26.4% compared with 29.0%. Foreign residents make up 9.3%.
Overture Maps data show 80 healthcare facilities in Grosseto (0.98 per 1,000 residents, above the provincial average of 0.69) and 124 sports facilities. The Ministry of Health lists 26 pharmacies, 0.32 per 1,000 residents, below the provincial average of 0.43.
The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for Grosseto too, so the report can reach the sheet and parcel numbers (foglio and particella) from an address. On a plain crossed by a large river and facing the coast, flood and landslide hazard and the local price range should be checked at the precise address.

Earthquakes
For Italy's Civil Protection Department, Grosseto is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Only 10 of 28 municipalities in the province are in zone 4.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.065 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.
Landslides and flooding
Landslide and flood risk changes from one street to the next, even within the same municipality: for this reason we do not summarise it as a single figure for the whole of Grosseto.
The report checks the exact address against the ISPRA national maps and tells you in plain words whether the building falls within an at-risk area. The official map is also available on IdroGEO.
House prices
We do not publish price tables by municipality. The report gives the minimum and maximum price per square metre for the address's zone, from the Revenue Agency's OMI valuations, with the reference half-year. It is a range for the zone, not the value of a specific home.
Population
Compared with the 2011 census, the resident population has grown by 3.6%. The estimated average age is 48 years, lower than the province average (49). 26% of residents are over 65 (the regional figure is 26%). Foreign residents make up 9.3% of the population. On average, a household has 2.1 members.
Services
In the official Ministry of Education and Ministry of Health lists, Grosseto has 71 schools and 26 pharmacies. The Overture Maps data also lists 55 grocery shops and supermarkets, 80 healthcare facilities, 124 sports facilities and 34 parks and green areas.
There are 1.0 healthcare facilities per 1,000 residents, more than the province average (0.7).
This data is gathered from several providers: services may be missing or closed businesses may still appear. The report counts services within 500 metres and 1 kilometre of the address.
Public transport
We do not yet have open public transport timetables for this municipality: the report says so explicitly, without inventing distances.
Land registry
The Revenue Agency publishes the cadastral maps for Grosseto: the report finds the building's parcel, that is its sheet and parcel number, starting from the address.
