Castel San Lorenzo, vines and olives above the Calore valley

Castel San Lorenzo gives its name to a controlled designation of origin (DOC) wine, and the landscape shows it: vineyards and olive groves cover the hills running down to the Calore valley, in inland Salerno province, between the Alburni mountains and the Cilento. The village lies at around 350 metres, with a compact centre and many country houses.

Buyers will find detached houses with land, village houses on several floors and some farm buildings to restore. Daily life needs a car: for work, secondary schools and the hospital people travel to the larger towns of the Sele plain or the Cilento. The data list 3 school sites and 2 supermarkets.

The population is falling clearly: Istat, the national statistics office, counts 2,201 residents in 2023, down 16.4% on 2011. The average age is 48.5, above 45.2 for the province, and over-65s make up 28.9%. Foreign nationals account for 5.1%. Declared incomes are below the Salerno average.

Castel San Lorenzo is in seismic zone 2, like 96 other municipalities in the province of Salerno, with expected ground acceleration of 0.108 g. If you plan to turn a farm building into a home, have the structure assessed before the design stage, not once work has started.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps: the report finds the land parcel from the address and checks the official landslide and flood maps for that plot.
