San Giuliano del Sannio, inland Molise south of Campobasso
For people in San Giuliano del Sannio, Campobasso is the town that matters: the regional capital is close, and it is where they go for work, hospital care, secondary schools and university. The village lies in inland Molise, south of Campobasso, at around 600 metres, among hills farmed for cereals and fodder, pasture and woodland, in the direction of the border with Campania.
Houses in the centre are built of stone and masonry, often on two or three floors, while those built in recent decades line the roads into the village. It is in climate zone E, with cold winters and some snow, so efficient heating and good insulation make a real difference to energy bills.
In 2023 San Giuliano del Sannio had 981 residents, down 6.6% from 1,050 in 2011, according to Istat, the national statistics office. The average age is 48.3, close to the 47.6 of the province of Campobasso, and over-65s make up 27.0%, against 26.5%. Foreign residents are 4.9%.
Earthquakes are the point to look at most carefully. San Giuliano del Sannio is one of the 11 municipalities in the province in seismic zone 1, the highest class used by the Civil Protection Department, and expected ground acceleration in the built-up area is 0.247 g. Before buying, find out when the house was built, whether it has been upgraded to resist earthquakes and what paperwork backs that up.
The Revenue Agency publishes the cadastral maps for the municipality: the report starts from the address, finds the land parcel and compares it with the official landslide and flood maps.
