Arcidosso, the castle and chestnut woods of Monte Amiata

The Aldobrandeschi castle towers over the old village of Arcidosso, on the Grosseto side of Monte Amiata, at around seven hundred metres. Chestnut and beech woods surround it, and higher up is the mountain that brings snow and visitors in winter. David Lazzaretti, the 19th-century preacher who founded a community on nearby Monte Labbro, was born here, and the municipality is also home to Merigar, a centre of the Dzogchen Buddhist community.

Buyers will find stone houses in the old village, with steps and narrow lanes, and more recent homes along the roads leading down from the centre. Grosseto is about an hour away by car, and for many services people also use Castel del Piano, right next door. Climate zone E means cold winters, so heating and insulation for a stone house should be factored into the price.

In 2023 there were 4,227 residents, down 2.0% since 2011. The average age is 48.0, a little below that of an elderly province like Grosseto (49.1), and over-65s make up 26.0% against 29.0%. Foreign residents account for 18.1%. Average declared incomes are below the provincial average.

The province of Grosseto has 2 municipalities in seismic zone 2, 16 in zone 3 like Arcidosso and 10 in zone 4, according to the Civil Protection Department. The expected ground acceleration in the built-up area is about 0.140 g. In the old village houses often lean on each other, so work on one building can affect its neighbours: ask the seller what has been done to the structure.

The Revenue Agency (Agenzia delle Entrate) cadastral maps are published. On the slopes, the report checks gradient and the official landslide maps for the individual plot.

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