Chiusdino, the Val di Merse hills and San Galgano

Chiusdino is a municipality in the province of Siena, in the wooded hills of the Val di Merse, south-west of the city. The old village stands on a hill above five hundred metres; down on the plain within its territory are the roofless abbey of San Galgano and the round chapel of Montesiepi with its sword in the stone, which draw many visitors.

The municipality is large and thinly populated, with plenty of woodland and scattered farms. Buyers here often want a farmhouse with land or a village house, to live in or for holidays. Siena is within driving distance, but for everyday services distances count. With a farm property, check the water supply, wastewater disposal, access roads and the state of the buildings. Incomes are below the provincial average.

Istat, the national statistics office, counts 1,707 residents in 2023, 9.1% fewer than in 2011. The average age is 47.9, similar to 47.6 for the province, and over-65s make up 28.8%. Foreign residents account for 18.4%.

Chiusdino is in seismic zone 3, like 31 municipalities in the province of Siena, and the expected ground acceleration in the built-up area is 0.140 g. In stone farmhouses, what matters is how walls and floors are tied together and the condition of the timber roofs.

The Revenue Agency (Agenzia delle Entrate) cadastral maps are published. The report traces the address to the plot and reads slope, landslides and flooding on the official maps, useful in a landscape of hills and valley floors.

Earthquakes

For Italy's Civil Protection Department, Chiusdino is in seismic zone 3, a zone where strong earthquakes are possible but rare. Most municipalities in the province (31 of 35) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.140 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.
