Castellina in Chianti, the fortress on the Chiantigiana road
Castellina in Chianti is one of the historic municipalities of the Chianti Classico area, on the Chiantigiana road between Siena and Florence, with Siena about twenty kilometres away. The village is built along a ridge at around 580 metres, around its medieval fortress, and has a feature that surprises visitors: the via delle Volte, a covered walkway running along the old walls. Just outside the centre is the Etruscan burial mound of Montecalvario.
The rest of the area is hills planted with vines and olives, woodland and scattered farms, with hamlets such as Fonterutoli. The market mirrors the landscape: restored farmhouses and estates, often with land and much sought after by foreign buyers; flats in the old centre; and few new homes. With a farmhouse, be clear about boundaries, rights of way, wells and septic tanks, and exactly what the sale includes among vineyard, olive grove and farm outbuildings.
According to Istat, the national statistics office, there are 2,616 residents (2023), down 8.6% on 2011. The average age of 47.3 is in line with the province of Siena (47.6). Foreign residents make up 16.1%, a high share for a hill municipality, and declared incomes are close to the provincial average.
Castellina is in seismic zone 3, with an expected acceleration of 0.120 g. In stone farmhouses, which have often been extended over time, it is worth having a surveyor check how the old and added parts are tied together, as well as the state of the roofs. Climate zone E brings cool winters.
Revenue Agency cadastral maps are published. In the Chianti hills the slope changes from one farm to the next, and the report reads the official maps for the address.
