You have to go in the Museum of the Treasure of St. Januarius that is more precious than Queen Elizabeth’s treasure. The treasure of St. Januarius has been saved by the Deputation for many centuries.

The Chapel of Neapolitan people

It is in the cathedral but it does not belong to the Church. The Royal chapel is independent. There are many paintings, silver busts, the relics of the Saint patron of the town and it is a baroque masterpiece. Besides, it has a wonderful acoustics and it was the second conservatory in Naples. Unmissable.

St. Januarius and his miracle

St. Januarius is a special saint because , for Neapolitan people, he represents the hope, the devotion, the intimacy, the power and popular pride. Every year, the three dates of his miracle are inexplicable and also his history is mysterious and fascinating.

Small museum which is dimly lit but to great effect as this highlights the shine of the amazing treasures found here. Cheap entry around €6, quiet early in the day.

I'm a local, living in a little town distant a few km from Naples and this Musem. I'm 44 years old and i did feel ashamed for viewing such a beauty only after so much time. The treasure kept in this Museum is amazing and San Gennaro is one of the most iconic figure of Naples. After my visit i started to understand better why. I suggest to visit the museum with a guide, for me made a huge difference. Without a guide, may be you don't fully understand the meaning of the exposed masterpieces that melt with the mystery and glory of this Saint.
