Museum of the Treasure of San Gennaro
The Museum of the Treasure of San Gennaro in Naples houses one of the most extraordinary collections of sacred art in Italy, assembled over four centuries by the Deputazione of the Royal Chapel of the Treasury in the Cathedral of Naples. Built around the veneration of the city's patron saint Januarius (San Gennaro), whose liquefying blood is among the most celebrated Catholic phenomena in the world, the museum displays the spectacular gold, silver, gem-encrusted votive offerings and liturgical objects donated by the Neapolitan faithful and their rulers since the 17th century.

Overview
The Treasure of San Gennaro is custodied by the ancient lay Deputazione, a body founded in 1527 after the plague that devastated Naples and renewed after the eruption of Vesuvius in 1631 ravaged the city, sparing it only — in popular belief — through the intercession of the saint. The museum adjoining the Royal Chapel presents the full magnificence of the treasury: golden busts, jewelled miters, chalices, reliquaries, and ex-votos that together constitute one of the richest collections of Baroque goldsmithing in Europe. The collection is estimated to be worth several billion euros and is entirely owned by the people of Naples through the Deputazione.
History
San Gennaro, the bishop of Benevento martyred around 305 AD, became the patron saint of Naples during the early medieval period. The tradition of the liquefaction of his blood — preserved in two sealed ampullae — is first documented in the late 14th century. The Royal Chapel of the Treasure, built between 1608 and 1646 as a votive offering after repeated disasters, became the ceremonial centre of Neapolitan civic and religious life. Over the following centuries, rulers and citizens alike donated precious objects to the treasury, creating the extraordinary accumulation of sacred art that the museum now displays.
What you see
The museum's permanent display includes the silver-gilt bust reliquary of San Gennaro (1305), one of the earliest and most remarkable examples of Neapolitan goldsmithing; the jewelled miter donated by Cardinal Ruffo; a collection of gem-encrusted pectoral crosses; and extraordinary Baroque chalices and monstrances by leading Neapolitan goldsmiths. The adjacent Royal Chapel, decorated with frescoes by Domenichino and Giovanni Lanfranco, is one of the finest Baroque interiors in southern Italy and forms an integral part of the visit.
Cultural significance
The Treasure of San Gennaro is inseparable from Neapolitan civic identity: the biannual liquefaction ceremony continues to draw vast crowds and remains a live expression of popular Catholicism. As an art collection it ranks among the finest assemblages of sacred Baroque goldsmithing in the world, comparable to the treasuries of major European cathedrals, and it remains entirely in the hands of the Neapolitan people — never having passed to the state or the Vatican.
