Marciano della Chiana, a village above the Valdichiana
Marciano della Chiana lies in the Valdichiana, the large reclaimed valley between Arezzo and the border with Umbria. The village sits on a gentle rise above the plain, surrounded by fields of cereals and sunflowers and olive groves, and keeps a small, compact historic core. Arezzo is the reference for work and services, and the A1 motorway, which runs along the valley, puts Florence and Rome within reasonable reach.
The Valdichiana is an area of farms and small businesses, and also popular with people looking for a country home in Tuscany. In Marciano the supply ranges from houses in the centre to detached homes built in recent decades and farmhouses, often the old tenant farmers' houses of the land reclamation era, either still to be restored or already renovated.
In 2023 there were 3,452 residents, up 0.9% on 2011, or 30 more people, according to Istat, the national statistics office. The population is younger than the provincial average: an average age of 45.1 against 47.6, and over-65s at 22.0% against 26.6%. Foreign residents are 9.4%. Average incomes are below the provincial average.
Most municipalities in the province of Arezzo are in seismic zone 2, and Marciano is one of them: zone 2, with an expected ground acceleration of about 0.150 g. In a stone or brick farmhouse, ask whether the restoration also dealt with the structure.
The Revenue Agency publishes the cadastral maps. On the reclaimed plain, crossed by canals and ditches, the report checks the official flood maps for the address.
