When it comes to Rome, most of us think of stunning piazzas, iconic landmarks, and breathtaking art. But sometimes, it’s the underground layers of history that really give you a sense of how long this city has been alive. This Santa Maria Maggiore Underground Tour offers a rare peek beneath one of Rome’s major basilicas, revealing archaeological remains and early Christian foundations few get to see.
What caught our eye are two standout features: first, the chance to step beneath the surface of a famous basilica and explore parts of Rome that are usually off-limits; second, the expertise of the guides, who bring the site’s history vividly to life. However, it’s worth mentioning that the tour isn’t accessible for everyone—if you have mobility challenges, this might not be the right fit.
This experience is perfect for history buffs, architecture lovers, or anyone curious about Rome’s quieter, more mysterious side. If you’re okay with some uneven paths and want a deeper understanding of early Christian Rome, this tour could be just what you’re looking for.

What the Tour Offers

The Santa Maria Maggiore Underground Tour is all about uncovering what lies beneath this iconic basilica. You begin by meeting at the Piazza di Santa Maria Maggiore, passing through security controls where your tickets are checked—so no skipping lines here, but the process is straightforward. Once inside, you won’t just admire the basilica’s impressive façade; you’ll descend into the underground chambers, which are believed to be the precursor to the church as it stands today.
