Castiglion Fiorentino, a walled hill town above the Valdichiana

Castiglion Fiorentino sits on a hill overlooking the Valdichiana, the broad valley south of Arezzo, on the road that leads on to Cortona. At the top, inside the walls, stands the Cassero with its tower; just below is the main square, where a loggia attributed to Giorgio Vasari opens onto the view. The municipality is large and spreads down into the plain and the surrounding hills, which include the castle of Montecchio Vesponi.

Buyers face very different options. Inside the walls the buildings are old, with steep stairs and little parking, and they need a careful look at structure and heritage restrictions. The newer districts at the foot of the hill suit people who commute to Arezzo, helped by the station on the slower Florence-Rome railway line. Out in the countryside there are farmhouses, many already restored, where road access, water supply and drainage are the practical questions.

At the end of 2023 the town had 12,865 residents, down 2.3% since 2011, a modest decline. It ranks number 6 by population among the 36 municipalities of the province of Arezzo. The average age, 46.8, is slightly below the provincial figure of 47.6, and foreign residents make up 10.7%. Average declared incomes are a little below the provincial average.

Earthquake risk deserves attention. The town is in seismic zone 2, as are 23 other municipalities in the province, with expected ground acceleration of 0.155 g. In stone houses and old farm buildings, what counts is the work done over the years, such as new roofs, tie rods and structural strengthening, so ask to see the building permits before you sign.

The Chiana plain was drained over the centuries and is crossed by canals. Near watercourses the report checks the official flood maps, and on slopes the landslide maps. The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, so the report goes from the address to the land parcel.

For anyone buying in Castiglion Fiorentino, 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.
