San Gregorio Magno, hill farming country in the upper Sele

In the eastern hinterland of the province of Salerno, not far from Basilicata, San Gregorio Magno sits on high ground at around four hundred and seventy metres, surrounded by fields, olive groves and pasture. It is a village of farming and livestock, and for hospital care, secondary schools and offices people go to the larger towns of the Sele valley or towards Salerno.

Here earthquakes are the first issue. San Gregorio Magno is in seismic zone 1, the highest, together with 17 other municipalities in the province, and the expected ground acceleration in the built-up area is about 0.248 g. The village was largely rebuilt or repaired after the 1980 earthquake, so many houses have a documented history of works: a buyer should ask for the reconstruction file, the structural sign-off (collaudo) and any later work. For older houses untouched since then, checking the structure matters even more.

The population is falling. In 2023 there were 3,892 residents, down 11.9% from 4,417 in 2011. The average age is 47.8 against 45.2 for the province, over-65s make up 28.3% against 22.7%, and foreign residents just 1.4%. Average declared incomes are well below the provincial average.

The climate is that of the inland hills (climate zone D), with cool winters. The land has some steep slopes and scattered country houses: access, gradient and landslide hazard need looking at case by case, and the report checks them for the address along with the flood maps.

The Revenue Agency (Agenzia delle Entrate) cadastral maps are published, and the report traces the address back to the building's plot.

For anyone buying in San Gregorio Magno, 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.
