San Nazzaro, a small hill village in the Sannio
San Nazzaro is a small municipality in the Sannio hills, not far from Benevento. The village sits at around 500 metres among fields, olive groves and vineyards, and daily life revolves around the provincial capital: jobs, secondary schools, offices and the hospital are there, within an easy drive.
The housing stock is mostly detached homes and village houses from different periods. For a buyer, the structure is the place to start: year of construction, any work carried out after past earthquakes, certificates and structural sign-offs. The climate zone is D, with winters that are not harsh but damp on the hills.
According to Istat, the national statistics office, there were 825 residents in 2023, 89 fewer than in 2011, a fall of 9.7%. The average age of 45.7 is just below the provincial 46.5, and over-65s make up 22.5% against 24.6% for the province. Households average 2.42 people. Declared incomes are above the average for the province of Benevento.
Earthquakes are the main point. San Nazzaro is in seismic zone 1, the highest class on the Civil Protection scale, like 48 of the 78 municipalities in the province, and the expected ground acceleration in the village is about 0.249 g. Before buying, have the house inspected by an engineer or surveyor and ask whether the building was designed to seismic standards or later upgraded.
On the Sannio hills, slope stability can change over short distances, so the report checks the official landslide maps for the address. The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps here, and the report traces the land parcel from the address.

For anyone buying in San Nazzaro, 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.
