San Leucio del Sannio, hills just south of Benevento
San Leucio del Sannio is a hill municipality a few kilometres south of Benevento, among fields, vineyards and olive groves, at around 370 metres. It is a small place whose life is closely tied to the provincial capital: secondary schools, the hospital, offices and much of the work are in Benevento, a short drive away.
People buying here usually want a detached house with a garden or land, within easy reach of the city but away from its traffic. The centre has older masonry houses, and around it are villas and homes from recent decades spread along the country roads. For these, check carefully that the house matches its building permits and the cadastral floor plan, a useful check anywhere in the area.
The population is falling: 2,897 residents in 2023, 10.5% fewer than in 2011. The mean age (46.6) is the same as the province, 24.6% are over 65 and foreign nationals make up 2.3%. Households average 2.38 people, and declared incomes are slightly below the provincial average.
The Sannio is one of the most earthquake-prone parts of Campania. San Leucio is in zone 1, the highest, like 47 other municipalities in the province, and the expected ground acceleration is 0.235 g. For any building, old or new, ask for the structural design or details of upgrading work and have a surveyor go through them. The report adds the official landslide and flood maps for the address.
