Centro Storico di Napoli
The most densely built, most continuously inhabited, and most architecturally layered urban UNESCO World Heritage Site in the world — Naples (UNESCO WHS 1995) has been inhabited for 2,500 years on the same street grid, accumulated 1,700 churches, buried two Graeco-Roman cities underground (Neapolis below the Decumani, Cumae at the edge of the plain), and produced the world’s most complex street-level vertical stratigraphy anywhere outside Rome.

Key facts
- The Spaccanapoli axis (why the straight line you see on the map is the most important street in Italian history): Spaccanapoli (literally “Naples-splitter”; formal name: Via Benedetto Croce + Via San Biagio dei Librai + Via Vicaria Vecchia; the southern Decumano Inferiore of ancient Neapolis) is the most historically significant single street in Italy that is not Via Appia — it was laid out by Greek colonists from Cumae in approximately 470 BCE as the southern main street of their new colony; the street has been continuously occupied since that moment; the current buildings above it range from 13th century CE to 20th century CE; walking Spaccanapoli from the Gesù Nuovo (1601 CE; Jesuit church with the diamante-faceted stone exterior) to the Basilica di Santa Chiara (1310 CE; Robert of Anjou; the largest church in Naples; the destroyed and rebuilt Gothic interior; the extraordinary 18th-century majolica cloister behind the church — the most colourful and completely tiled cloister garden in Italy, added 1739 CE by Domenico Antonio Vaccaro, each column and bench covered in pastoral Neapolitan scenes in tin-glazed earthenware) takes approximately 45 minutes and passes 2,500 years of Neapolitan civilization at street level
