San Pietro al Tanagro, beside the river in the Vallo di Diano
San Pietro al Tanagro lies in the Vallo di Diano, the broad plain enclosed by mountains in the south of the province of Salerno, crossed by the river Tanagro. The village is on the edge of the valley, with its centre on the slope and farmland spreading across the flat ground. The A2 motorway runs along the valley, putting Salerno within reach to the north and Calabria to the south.
The valley offers buyers two different situations. On the slope, in the centre, there are stone houses with uphill access and some homes needing renovation; on the plain and along the roads, villas and newer houses, easy by car but worth checking carefully for their closeness to the river and canals. Winters in the valley are cold and damp (climate zone D).
There are 1,645 residents (2023), down 5.3% since 2011 according to Istat, the national statistics office. The average age of 45.0 is in line with the province (45.2), with over-65s at 23.6% and foreign residents at 5.8%. Declared incomes are slightly below the provincial average.
The municipality is in seismic zone 2, like 97 of the 158 municipalities in the province of Salerno, with an expected ground acceleration of 0.186 g. The Vallo di Diano has a significant earthquake history: for an older building, ask for the design, the year of construction and any improvement work.
The Revenue Agency publishes the cadastral maps. The report finds the land parcel and checks the official landslide and flood maps for that address, the former on the slope, the latter on the Tanagro plain.
