San Martino Sannita, hills south-east of Benevento

A few kilometres south-east of Benevento, San Martino Sannita covers a stretch of hillside at around 450 metres, among vineyards, olive groves and wheat fields. Many residents live here and work or study in Benevento, a short drive away.

Around the older core there are more recent detached houses and small blocks of two or three storeys. For anyone wanting a house with a garden close to Benevento it is worth a look; check the year of construction and the planning paperwork, especially for extensions and converted lofts.

Figures from Istat, the national statistics office, give 1,142 residents in 2023, down 10.6% on 2011. The average age of 46.8 is almost exactly the provincial figure (46.5), and 24.3% of residents are over 65. Declared incomes are in line with the provincial average.

Earthquakes are the main issue for buyers. San Martino Sannita is in seismic zone 1, the highest class on the Civil Protection Department scale, like 47 other municipalities in the province, and expected ground acceleration in the village is 0.249 g. For houses built before the most recent seismic rules, ask whether they have been assessed or strengthened, and for the paperwork.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for the municipality. The report finds the plot from the address and reads gradient and landslide hazard on the official maps, which on the hill vary from one street to another.
