San Gennaro all’Olmo, Naples

San Gennaro all'Olmo is a Baroque church in Via San Gregorio Armeno in Naples featuring the decorative style typical of this period. The interior displays polychrome marble, ornamental stucco, and patterned tile floors characteristic of the era.

The church was founded in the seventh century by Bishop Sant'Agnello as Naples' first sanctuary dedicated to Saint Januarius. Armenian monks fleeing Byzantine persecution arrived in the eighth century, bringing sacred relics to the site.

The church's name comes from a tall elm tree that once stood at its entrance, providing shade to visitors passing by. This connection between the religious space and the natural landscape shows how the place was woven into daily city life.

The building is no longer used as an active church but is managed by the Fondazione Giambattista Vico and hosts cultural events throughout the year. Check what programs are currently available to see if you can visit during one of these scheduled activities.

The church stands on Via San Gregorio Armeno, a street known for its artisan workshops and craft traditions that remain active today. This location connects the building to a neighborhood where traditional manual skills and production methods have survived through generations.
