Castiglione della Pescaia, canal harbour, pinewoods and Punta Ala
A canal harbour lined with fishing boats, a walled village on the hill and long beaches backed by pine woods: Castiglione della Pescaia is one of the busiest resorts on the Maremma coast, north-west of Grosseto. The municipality, though, is much larger than the town. It includes Punta Ala, with its marina, villas and golf course, the hill villages of Tirli and Buriano, and Vetulonia, site of an ancient Etruscan city. Between the sea and the plain lies the Diaccia Botrona, a protected wetland.
For a buyer, this is a second-home market, with high prices near the sea and at Punta Ala and more affordable ones inland. In summer the population multiplies; in winter many houses stay shut. The data shows it, with 197 bars and restaurants recorded, many times the provincial average per head. Anyone planning to live here year-round should check which services stay open out of season and how far it is to Grosseto for the hospital and offices.
At the end of 2023 there were 7,105 permanent residents according to Istat, the national statistics office, almost the same as in 2011 (up 0.4%). It is an older population: an average age of 51.3 against 49.1 for the province, over-65s at 30.7%, and small households of 1.89 people on average. Declared incomes are above the Grosseto average.
Seismically, the coast is calm. Castiglione is in zone 4 on the Civil Protection scale, the lowest, like 9 other municipalities in the province, and the expected ground acceleration is about 0.053 g. In houses near the sea, salt air, damp and upkeep of facades and window frames matter more.
The low reclaimed land around the Diaccia Botrona and towards the river mouth is the first to check for flooding, while the hill villages have steep slopes. The report checks the official landslide and flood maps for the address and finds the plot on the Revenue Agency's cadastral maps.

Overview
Castiglione della Pescaia is a municipality in the province of Grosseto, in Toscana. At the end of 2023 it had 7,105 residents, ranked 8 of 28 municipalities in the province.
Earthquakes
For Italy's Civil Protection Department, Castiglione della Pescaia 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 0.053 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.

Compared with the 2011 census, the number of residents is nearly unchanged. The estimated average age is 51 years, higher than the province average (49). 31% of residents are over 65 (the regional figure is 26%). Foreign residents make up 8.5% of the population.
