Teggiano, a hilltop town in the middle of the Vallo di Diano
The Vallo di Diano is a long plain ringed by mountains in the south of the province of Salerno, on the border with Basilicata, and Teggiano stands on a lone hill right in the middle of it. The town's ancient name was Diano, which gave the valley its name. The historic centre, more than six hundred metres up, is a web of alleys, churches and stone doorways with a castle at the top; down on the plain, hamlets such as Prato Perillo, San Marco and Pantano have grown up.
The A2 motorway runs along the valley with junctions a few kilometres away, so Sala Consilina, Polla and the other towns of the Vallo are easy to reach. Salerno and the coast, on the other hand, are far. Buyers choose between a house in the old town, with thick walls, steps and hardly any parking, and a newer house on the plain, easier if you drive every day.
The population has dropped sharply, from 8,182 in 2011 to 7,077 in 2023, a fall of 13.5%. The average age is 48.1 against 45.2 in the province, over-65s are 27.0% and foreign residents 5.2%. Declared incomes are well below the provincial average. Schools, on the other hand, are plentiful in Overture Maps data, 2.12 per 1,000 residents against 1.24, partly because the municipality is split into several centres.
The Vallo di Diano is earthquake country. Teggiano is in seismic zone 2 on the Civil Protection Department's scale, with an expected ground acceleration of about 0.186 g, and in the province of Salerno 18 municipalities are in zone 1. For a house in the old town, find out what structural work has been done over the years and under which permits; for concrete buildings on the plain, the design and inspection documents are what count.
The valley floor, crossed by the Tanagro river and drainage channels, was once marshland: in the lowland hamlets look at the flood maps, on the sides of the hill at the landslide maps. The report reads both for the address and uses the Revenue Agency (Agenzia delle Entrate) cadastral maps, which are published here too.

For anyone buying in Teggiano, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.
