Naples is full of off-beat religious sites that can be difficult to find. This private tour visits the Church of Santa Luciella ai Librai, hidden deep in the heart of the historic center. Once a place of cult worship, the church holds the “skull with ears,” a skull-relic with mummified cartilage on each temple resembling ears. Meet on Via San Gregorio Armeno, explore the church with a guide, and finish your tour at the Palazzo Venezia nearby.
