ABSTRACT
The vineyard contains more than 7 Km of retaining walls with a height over 3 m. The system of retaining walls shows evident signs of degradation because of lack of any maintenance and uncontrolled runoff of water; the densely inhabited underlying built environment is exposed to a high landslide risk. Someone says that it is the only oriental city without a European district; it is indeed the only large European city whose historical center is still inhabited by people and not only by banks, offices, shopping malls. A review of the history of Napoli through three millennia, as seen through the lenses of geotechnical engineering, has been presented by Aversa et al. The system of retaining walls shows evident signs of degradation because of lack of any maintenance and uncontrolled runoff of water; the densely inhabited underlying built environment is exposed to a high landslide risk.
