Arpaia, the Caudine valley on the Via Appia

Arpaia is one of the municipalities of the Valle Caudina, in the province of Benevento, crossed by the Via Appia on the stretch linking the Caserta and Naples area with Benevento. Tradition places the Caudine Forks in this valley, the pass where the Samnites forced a Roman army to surrender. Today the village is small and compact, and many residents work elsewhere.

The municipality covers little land, much of it built up, with houses along the main road, apartment blocks and detached homes climbing towards the lower slopes of the hills. For buyers, noise and traffic near the Appia matter, as do slope and access for houses higher up: the report measures the gradient at the address and reads the official landslide and flood maps.

Figures from Istat, Italy's national statistics office, show 1,992 residents at the end of 2023, down 1.2% on 2011, so almost stable. It is a young municipality: an average age of 42.8 against 46.5 for the province, and over-65s at 17.8% against 24.6%. Foreign residents make up 4.9%. Declared incomes are below the provincial average. The climate zone is D.

Arpaia is in seismic zone 2, with a fairly high expected ground acceleration in the built-up area of 0.181 g. The Sannio is a significant earthquake area, so before buying ask for the build year, the structural design and records of any strengthening work.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report goes from the address to the land parcel.
