The Cathedral is a complex rather than one façade. Santa Restituta, the Baptistery of San Giovanni in Fonte, medieval and Baroque chapels, archaeological traces and repeated rebuilding require a route that distinguishes phases.
San Gennaro’s cult connects liturgy, civic identity, treasury, procession and collective memory. The Chapel and Treasure were governed through institutions with their own history; devotion should not be reduced to spectacle around the liquefaction rite.
Nearby foundations broaden the story. The Girolamini join worship to music and books; Pio Monte della Misericordia connects art to organised charity; Donnaregina and San Giovanni a Carbonara record female patronage, dynastic memory and changing museum use.
Check worship and museum schedules separately, then move slowly: the sacred city becomes legible through thresholds, chapels, archives and present communities, not through a checklist of relics.
