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.

Januario Gagliardi


Well I'm suspicious to say something about the cathedral of the saint that my name and my history came from. Putting the emotions beside, I really get impressed by the conservation of the images walls and the whole cathedral. Its seems like it was made not so long time ago and this makes you feel like been part of that. Enjoy the experience because it's very pure.

Simply unbelivable. None knows about this and a vist to Naples should be whorth Just for this. I am Sorry for our beloved Queen,She can't have those jewels.

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.
