Pollena Trocchia, on the slopes of Monte Somma towards Naples

The first thing to know is that Pollena Trocchia lies in the red zone of Vesuvius. The national emergency plan provides for the precautionary evacuation of every resident if an alert is declared. This applies to every address in the municipality and is worth knowing before you buy, even though the volcano is monitored around the clock.

The town sits on the northern slope of Monte Somma, the older ridge of the Vesuvius complex, about a dozen kilometres from central Naples. Its name joins the two original villages, Pollena and Trocchia. Houses climb from the plain towards the woods of the Vesuvius National Park, and a single street can pass from recent blocks of flats to old courtyard houses. People work in Naples or the towns around the volcano and mostly travel by car.

The population is young, as in much of the Naples area. People over 65 make up 19.3%, just below 20.0% in the metropolitan city, the average age is 42.7 and households are large, 2.85 people on average. There were 12,723 residents in 2023, down 5.9% since 2011 according to Istat, the national statistics office. Foreign residents are few, 1.8%. Schools are well provided, 0.94 per 1,000 residents against 0.87.

Besides the volcano there are earthquakes. Pollena Trocchia is in seismic zone 2 on the Civil Protection map, like 75 other municipalities in the metropolitan city, with expected ground acceleration of 0.171 g. Before buying, ask for the structural design, the year of construction and whether the building has been assessed or strengthened.

On the slopes of Monte Somma, heavy rain can wash mud and debris down the gullies that run towards the valley, a known problem across the Vesuvius area. The report checks landslide and flood maps for the exact spot. The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, so the report finds the land parcel.
