Castellina Marittima, alabaster hills above the coast
Castellina Marittima looks down on the sea: the village sits in the hills behind the Livorno coast, at around 375 metres, in the south of the province of Pisa. Its name has been linked for centuries to alabaster, quarried locally and then worked mainly in Volterra. Around it are woods, olive groves and fields, and the beaches are about twenty minutes away.
Buyers here are often looking for something between seaside and countryside. The centre has stone houses on sloping streets; outside it there are farms, restored farmhouses and detached homes. For isolated houses the access road matters, since in the hills it may be unpaved and steep, and so do the water supply and drainage where there is no public network.
There were 1,846 residents in 2023, down 7.0% since 2011. The average age is 48.8 against 46.9 in the province, over-65s make up 27.0% and foreign residents 7.8%. Declared incomes are below the provincial average.
All 37 municipalities in the province of Pisa are in seismic zone 3, Castellina included: the expected ground acceleration is 0.134 g, a moderate hazard. For an old farmhouse it is still worth asking for records of any strengthening work and having the roof and floors checked.
The climate zone is D, with mild winters. The Revenue Agency cadastral maps are published, and from the address the report identifies the land parcel and checks slope and the official landslide and flood maps.
