 | Januarius was Bishop of Naples, and is a martyr saint of the Roman Catholic and the Eastern Orthodox Churches.
The Treasure of San Gennaro contains a selection of the most important works donated to Saint Januarius by over 700 years of Popes, Emperors, and European Kings. The works have the highest artistic value: they were made using a huge number of precious stones, by the most eminent goldsmiths of the time. |  |
