Adjoining Naples Cathedral, the Museum of the Treasure of San Gennaro holds one of the world's most valuable collections of religious relics and jewels, given across centuries to the patron saint of Naples by popes, emperors, and monarchs. The crowning jewel is the 1713 Mitre of San Gennaro, studded with 3,326 diamonds, rubies, and emeralds, alongside the legendary Saint Januarius necklace adorned with gems donated by European royalty.
