The Deputation has always faced many vicissitudes and jurisdictional struggles, even to defend the right of patronage of the City on the Chapel. The history of the Deputation, full of events and activities, has disentangled for about four centuries until now: its role was not only of a mere guardian (not funding wars and suffering plunder), but especially that of promoter of many artistic activities, mainly Neapolitan, which developed and flourished, leaving an indelible imprint in the cultural world.

The task of Deputation of the Royal Chapel of Treasure is the respectful preservation of the ancient tradition and the recognition of its religious significance over time, not only for today, with its unifying and community value, but especially for future generations.

The Treasure of San Gennaro is considered as one of the most important in the world because the Deputation was not limited to collect donations indiscriminately, but has selected, directed stylistically, suggested and commissioned it following a logical and consequential line.

Probably, without this institution, tradition, history, culture and the extraordinary artistic heritage associated with the cult of San Gennaro, would not be preserved intact over time.

The opening of the Museum of the Treasure of San Gennaro is inserted in the main development activities and development of the territory that the ancient Neapolitan institution has always done.
