Rosignano Marittimo, from the hilltop village to Castiglioncello
The name refers to the hilltop village with its castle and tightly packed houses, but the municipality is a set of very different places on the coast south of Livorno. Rosignano Solvay, on the sea, grew up around the large chemical plant it is named after. Castiglioncello, to the north, is a holiday resort with villas among the pines and rocky coves. Vada, to the south, has long, shallow beaches and many campsites. Then there are Castelnuovo della Misericordia, Gabbro and Nibbiaia in the hills inland.
Buyers need to choose the place first, then the house. Castiglioncello has some of the highest prices on the Livorno coast and many homes are second homes. Rosignano Solvay and Vada have a steadier year-round life, with schools and shops open all year. The white beaches near the plant, famous for their colour, are linked to industrial discharges, and anyone considering a home there may want to look into environmental monitoring. The Tyrrhenian coast railway stops at the main villages and the coast road leads to Livorno and Cecina.
The population is older and shrinking. There were 30,033 residents in 2023, down 5.4% since 2011. The estimated average age is 49.8, above the provincial 48.7, and over-65s make up 29.4% against 28.1%. Foreign nationals are 6.8%. Average incomes are in line with the province.
In the province of Livorno municipalities are split between zones 3 and 4 of the Civil Protection classification: 13 are in zone 4, and only 6 in zone 3, Rosignano among them. The expected ground acceleration is about 0.118 g. By the sea, salt air and the upkeep of facades and balconies also matter.
The river Fine reaches the sea between Rosignano Solvay and Vada, and the low areas near its mouth need checking for flooding; in the hills inland, slope stability matters more. The report carries out both checks on the official maps, starting from the plot in the land registry of the Revenue Agency (Agenzia delle Entrate).
