Torrita di Siena, walled town in the Valdichiana and Montefollonico
Torrita di Siena is split between hill and plain. The historic centre, still largely enclosed by its medieval walls, stands on a rise above the Sienese Valdichiana, between Sinalunga and Montepulciano. Newer neighbourhoods and business areas have spread downhill towards the valley. Higher up, on the road towards the Val d'Orcia, lies the village of Montefollonico, a walled stone hamlet with its own market, including foreign buyers looking for a home in the countryside.
The two sides of the municipality mean two different property markets. In the main town and the newer areas towards the valley you find flats and houses for people who work locally, including in Valdichiana businesses. Farmhouses, country estates and homes in Montefollonico follow the prices of Tuscany's most sought-after countryside. The Valdichiana junction on the A1 motorway is a few minutes away, near Bettolle. The town stands at around three hundred and twenty-five metres, in climate zone D, with fairly mild winters.
Istat, the national statistics office, counted 6,969 residents in 2023, down 5.3% since 2011. The average age is 48.5 and 29.3% of residents are over 65, above the 26.9% for the province of Siena. Foreign residents make up 8.2%, below the provincial figure. Declared incomes are under the provincial average. Local services include 4 schools and 3 pharmacies, while for supermarkets people often go to neighbouring towns.
The Civil Protection Department places Torrita in seismic zone 3, like 30 other municipalities in the province, with an expected ground acceleration of about 0.146 g. With a stone farmhouse, find out how the roof and floors were rebuilt, whether tie rods or ring beams were added and whether extensions have planning consent; with a flat in town, the state of the building and its services matters most.
On the plain the report checks flood hazard along the Valdichiana drainage channels, and on the slopes landslide hazard. The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for Torrita.

For Italy's Civil Protection Department, Torrita di Siena 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.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
