San Gennaro and Naples could call, without fear of making mistakes, a relationship of faith and only love in the world that has lasted continuously for about sixteen centuries and is a rare example of the intense and heartfelt religiosity of a people. Events, legends and the same history of the city of Naples have always revolved around the "miracle" of liquefaction of the blood of the patron saint, polarizing not only the devotion of the people and that in real time occupied the throne of Naples, but also kings of other nations, of popes, the men of the church and many other distinguished foreign personalities who, in person, wanted to venerate the relics of the saint.

The history of the city of Naples is individually and lovingly intertwined with the cult of the patron saint so that the relationship, religious and cultural, has spread around the world, but what has characterized in a unique way this relationship is that, around the worship have flourished works of art of inestimable value. The witness to this worship and those pilgrimages are certainly the Deputation of the Royal Chapel of the Treasury, the Chapel of the Treasury and the real treasure of San Gennaro. The site of the Museum of the Treasure of San Gennaro wants first to disclose the cult of the patron saint of Naples and renew a tradition and a feeling distant in time, but at the same time is also an invitation to visit the extraordinary artistic treasures related to San Gennaro and become a solid point of reference for the many communities of the faithful, the Neapolitan and southern scattered around the world
