The legacy left by Saint Januarius, the patron saint of Naples, is incredible: history and legend, devotion and art come together in a unique form of alchemy. The museum area is over 700m2 and exhibits jewellery, statues, busts, precious fabrics and paintings of great value in the rooms below the Chapel of the Treasury. The museum displays the magnificent necklace of St. Januarius made from 1676 to 1929 and representing 250 years of European history. This special necklace was originally composed from 13 gold links with diamonds, emeralds and rubies, but was later enriched by adding gifts from kings and queens who have reigned over, or visited, Naples.
Another important piece is the mitre adorned with the jewels of St. Januarius, one of the most precious objects in the world. Created using the embedding technique and innovative precious stone cutting, it’s made up of 3,694 precious stones, 198 emeralds, 168 rubies and 3,328 diamonds; it weighs 18kg. The silver collection is also unique, consisting of over 70 pieces from 1305 to the contemporary age. It is almost entirely the work of masters of the Neapolitan school.
