Marigliano, on the plain between Naples and Nola

Between Naples and Nola the plain is almost entirely built up, and Marigliano occupies part of it, with Vesuvius clearly visible to the south. It is a municipality in the eastern hinterland of Naples, where the old centre, residential districts built from the 1970s onwards, industrial sheds and still-farmed fields sit side by side. The Circumvesuviana, the local commuter railway, links the town with Naples.

People who buy here are usually looking for lower prices than in the city and a larger flat, and accept a daily commute. Differences between areas are sharp: the outlying villages and districts have a different character from the centre, and it pays to visit them at different times of day before deciding. In buildings put up quickly in past decades, check that the work was properly permitted, the state of the systems and the condition of the shared parts.

There were 29,302 residents in 2023, down 3.1% since 2011. Households are large by Italian standards, 2.55 people, and the estimated average age of 43.3 is almost the same as the province (43.2). Foreign residents make up 3.9%. The 39 schools recorded work out at 1.33 per 1,000 residents against 0.87 in the province, while public green space is almost absent.

Earthquake hazard is the most serious issue. Marigliano is in seismic zone 2, like 76 municipalities in the metropolitan area of Naples, and expected ground acceleration in the built-up area is about 0.176 g, a medium-high value. The 1980 Irpinia earthquake caused damage across the whole Naples area. For a block built before the 1980s, ask for the design date, any structural work and the building's maintenance records.

Flooding is possible even on flat land, because roads and channels fill up quickly in heavy storms. The report checks the official maps for the individual address and measures from there the distance to schools, pharmacies and stops.

For anyone buying in Marigliano, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 96 inhabited census areas in Marigliano. Half of the residents live in areas scoring 64 or more.
