Castelfiorentino, in the Valdelsa between Empoli and Certaldo

Castelfiorentino is the largest town in the Florentine part of the Valdelsa, on the banks of the river Elsa halfway between Empoli and Certaldo. It has two distinct halves: the old core on the hill, gathered around its churches, and the newer town that spread down onto the flat land towards the river and the railway. Vineyards and olive groves cover the surrounding hills, and a town museum holds the frescoed wayside shrines painted by Benozzo Gozzoli.

The station on the Empoli-Siena line connects to Empoli and from there to Florence and Pisa, so the town is a realistic option for people working in the Florence area who want lower prices. Average declared incomes are well below the province of Florence. On the hill you will find old masonry houses, narrow streets and slopes; on the plain there are mostly apartment blocks and small houses, easier with a car but closer to the river.

Istat, the national statistics office, counted 17,262 residents in 2023, down 1.3% since 2011. The average age (46.8) is slightly below the metropolitan area and over-65s make up 25.8%. Foreign nationals account for 14.4% of residents. Schools (14 recorded) are more widespread than the provincial average, while pharmacies and healthcare facilities are a little thinner.

Castelfiorentino is in seismic zone 3 on the Civil Protection Department's scale, like 28 municipalities in the province; the most exposed, in zone 2, number 13. Expected ground acceleration is about 0.137 g. For masonry houses on the hill, ask how the roof is built and whether there are tie rods or strengthening works. On the Elsa plain the report checks flood-prone areas for the address, and it finds the land parcel on the Revenue Agency's cadastral maps.

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