Exploring Rome’s Hidden Depths: A Look at the Roman Houses of Celio Underground Tour
If you’re eager to uncover a side of Rome that most visitors miss, the Roman Houses of Celio underground tour offers a fascinating glimpse into the city’s lesser-known past. While many travelers flock to the Colosseum or the Vatican, this tour takes you beneath the Basilica of Saints John and Paul to explore over 20 underground rooms filled with well-preserved frescoes and ancient relics.
What we especially appreciate about this experience is how it combines archaeological discovery with storytelling. You’ll get a detailed look at everyday life in ancient Rome, as well as the stories of the martyrs John and Paul. Plus, the small group setting means more personalized attention from your guide and plenty of chances to ask questions.
However, one thing to consider is that the tour isn’t wheelchair accessible and has some restrictions on photography and bags inside the underground rooms. This means it’s best suited for curious travelers comfortable with a somewhat confined, indoor exploration. If you’re someone who enjoys history with a focus on authenticity and detailed storytelling, this tour could be a perfect fit.
This experience suits travelers who appreciate archaeological sites, historical context, and less touristy routes—especially those who want a comprehensive yet manageable glimpse into Rome’s early Christian and pagan past.
