Subbiano, on the Arno between Arezzo and the Casentino

Subbiano is the first town you reach following the Arno upstream from Arezzo into the Casentino, some fifteen kilometres from the provincial capital. The centre sits on the valley floor, with the river running through it; around it are hamlets in the hills and mountains, climbing towards the woods of the Alpe di Catenaia.

The Arezzo-Stia railway, which runs up the Casentino, has a station at Subbiano, and the main road gets you to Arezzo in about a quarter of an hour. That is why families who work in the city and want more room choose the town. What is for sale ranges from houses in the centre and small blocks on the valley floor to farmhouses in the hamlets, where roads and services take more time.

There were 6,340 residents at the end of 2023 according to Istat, the national statistics office, up 0.7% on 2011. The average age is 46.7 and over-65s make up 24.2%, fewer than in the province (26.6%); foreign residents account for 9.1%. Declared incomes are below the Arezzo average.

Subbiano is in seismic zone 2 on the Civil Protection scale, like 24 of the 36 municipalities in the province of Arezzo, with an expected ground acceleration of about 0.173 g. With a farmhouse or stone house, ask what structural work has been done and under which permits.

Here the Arno is still a valley river that rises fast after heavy rain: for homes near the banks the report checks the flood maps, for those in the hills the landslide maps. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the report goes from the address to the plot.

For anyone buying in Subbiano, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.
