Monticiano, woods and hills of the Val di Merse

Monticiano lies in the wooded hills south-west of Siena, in the Val di Merse area, where the Tuscan landscape of vineyards gives way to holm oak, oak and scrub. The old village is gathered on a hilltop at around 400 metres, surrounded by hamlets, farms and scattered houses along country roads. Siena is the reference point for work, university and hospital.

It is a large, sparsely populated municipality, chosen by people looking for nature and space: stone farmhouses, farms with land, flats in the old centre. For a farmhouse, the access road, water, drainage and rules on outbuildings matter; in the village, stairs and parking. Winters are cool (climate zone D).

Residents numbered 1,649 in 2023, up 9.6% on 2011 according to Istat, the national statistics office. The average age is 45.4, below the 47.6 of the province of Siena, and over-65s make up 24.1%. Foreign residents are 33.4%. Declared incomes are below the provincial average.

The municipality is in seismic zone 3, like 31 of the 35 municipalities in the province, with an expected ground acceleration of 0.140 g. For stone farmhouses, ask whether work has been done on walls, floors and roofs and whether it is documented.

The Revenue Agency publishes the cadastral maps. The report traces the land parcel from the address and checks the official landslide and flood maps, useful for farms near streams and on slopes.
