San Nicola Baronia, a village in Irpinia's Baronia
In the hills of the Baronia, in the eastern part of the province of Avellino, San Nicola Baronia stands at about 600 metres, with a compact centre and open farmland around it. For work and larger services, people drive to the nearby towns and to Avellino or Benevento, along provincial roads through the hills.
Compared with many villages in inland Irpinia, the population here has held up. There were 768 residents in 2023, down only 2.0% since 2011. The average age, 45.6, is even slightly lower than the provincial 46.2, and over-65s make up 24.9%. Foreign residents account for 4.9%. Average declared income is in line with the provincial figure.
For a buyer, the figure that matters most is seismic. San Nicola Baronia is in zone 1, the highest in the classification of the Civil Protection Department, like 58 of the 118 municipalities in the province, and the expected ground acceleration in the village is about 0.258 g. Before buying, ask for the structural design, the structural sign-off and the paperwork for any repairs, and if in doubt have a surveyor or engineer look at the building.
Alongside the older buildings in the centre there are more recent ones, in masonry or reinforced concrete. This is climate zone E: cold winters with the heating on for months, so the energy rating and the condition of the windows affect running costs.
The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for the municipality, and the report goes from the address to the land parcel. In the hills, landslide hazard changes from one slope to the next, and it is read from the official maps for the location of the house.
