Собор посвящен Св. Януарию, который очень почитаем неаполитанцами. Мы были с обзоной экскурсией, но можно и самостоятельно, времени займет не много.
The cathedral is dedicated to St. Januarius, who is very revered by the Neapolitans. We were with a sightseeing tour, but you can do it yourself, it won’t take much time.
