The Naples Underground Tour

What to see in NaplesNaples, in truth, is a tale of two cities. One, the narrow streets with seemingly no logic, full of bustling traffic. The other, more than 3,000 years old that curves, collapses, and hollows underground. Sixty percent of Neapolitan inhabitants live on top of more than seven hundred cavities underneath the city. These subterranean passageways include old Roman markets, theaters, grottoes, crypts, and former bomb shelters. Most of these undergrounds remain closed or barely discovered; many are even privately owned.

Neapolitan spelunkers dedicate themselves to the study of these cavities. Otherwise known as speleologists, they study the structure, physical properties, history, and life forms inside caves. They also study the processes by which caves form (speleogenesis) and how caves change over time (speleomorphology). The term speleology is also commonly known as caving, spelunking, or potholing.

For up-to-date information about Neapolitan spelunking activities, you can visit the Italian language website with up-to-date information on lectures and spelunking activities. Larry Ray also has a wonderful history of the Naples underground. Here are some of the sights to see:
