Guardistallo, Val di Cecina hills within sight of the sea
From the hills behind Cecina, Guardistallo looks out to sea: the village stands on high ground in the lower Val di Cecina, surrounded by vineyards, olive groves and woods, in the Montescudaio wine area. The coast, the Via Aurelia trunk road and Cecina station on the Tyrrhenian railway are a short drive away; Pisa and Livorno lie further north.
The market is typical of Tuscan hill country near the sea: houses in the village, often on several floors and with views, farmhouses and smallholdings scattered across the countryside, and some newer detached homes. Many buyers are looking for a holiday home. With farmhouses, check the roof, the services, access in the wet months and the planning status of outbuildings and extensions; with smallholdings, the boundaries and the agricultural use of the land.
There were 1,185 residents in 2023, 5.5% fewer than in 2011 according to Istat, the national statistics office. The village is older than the province of Pisa: an average age of 50.0 against 46.9, over-65s at 30.3% against 25.3%. Foreign residents make up 10.6%. Declared incomes are below the provincial average.
Seismic classification is uniform across the province of Pisa: all 37 municipalities are in zone 3 of the national scale. In Guardistallo the expected ground acceleration in the village is 0.128 g, a middling value, so for a stone or brick house it is worth knowing when the floors and roof were redone and whether any strengthening work has been carried out. The climate is zone D, with mild winters.
The Revenue Agency (Agenzia delle Entrate) cadastral maps are published, and the report links the address to its land parcel. In a landscape of clay hills and ditches, landslide and flood hazard are read on the official maps for the exact spot.

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