Beneath the dazzling sunlight and lively piazzas of Rome lies another world—quiet, shadowy, and filled with echoes of the past. This is Rome’s Underground, a labyrinth of ancient tunnels, crypts, and catacombs that reveal the city’s most mysterious and sacred side. While most visitors come for the Colosseum and the Vatican, those who descend below street level discover a hidden Rome that tells the story of early Christianity, forgotten emperors, and centuries of life and death beneath the Eternal City.
It’s hard to imagine that beneath modern Rome’s traffic and monuments runs an intricate web of ancient passageways, burial chambers, and sanctuaries. The origins of these underground sites date back to the early centuries of the Roman Empire. As the population grew, space became scarce—and the Romans began to dig.
The result? Miles of tunnels carved into soft volcanic rock called tufa, first used as quarries and later transformed into burial grounds and places of worship. During the persecutions of Christians, these catacombs became secret meeting places where believers gathered to pray, bury their dead, and keep their faith alive in silence.
Today, archaeologists and visitors alike are fascinated by this subterranean city—one that mirrors Rome above, but in darkness and stone.
There are more than sixty catacombs scattered beneath Rome, though only a few are open to the public. Each tells a different story, carved into the same tufa stone but filled with distinct symbols, frescoes, and relics of early faith.
Located along the Appian Way, the Catacombs of San Callisto are among the most extensive and historically significant. Founded in the 2nd century AD, they stretch for nearly 20 kilometers and once held the remains of 16 popes and countless Christian martyrs.
Walking through its narrow corridors, visitors see ancient inscriptions, Greek and Latin epitaphs, and simple yet moving frescoes depicting the Good Shepherd, the fish, and other early Christian symbols of hope and resurrection.
Just nearby lies the Catacombs of San Sebastiano, named after the soldier saint martyred for his faith. These catacombs are easier to navigate and feature both pagan and Christian tombs, showing how old Roman burial customs gradually evolved as Christianity spread.
Legend says that for a time, the relics of Saints Peter and Paul were kept here during periods of persecution, making this one of the holiest underground sites in Rome.
For those seeking a deeper, less touristy experience, the Catacombs of Domitilla are a must. Still containing bones of the faithful, this is the only catacomb where you can see an underground basilica—built in honor of Saints Nereus and Achilleus. Its walls are decorated with frescoes that bridge pagan and Christian art, symbolizing the cultural transition of a changing empire.
The underground of Rome isn’t limited to the catacombs. Several churches and archaeological sites across the city reveal multi-layered worlds beneath their floors, where time and history overlap.
Few places capture the layering of Roman history as perfectly as the Basilica of San Clemente. Above, you’ll find a stunning 12th-century basilica with golden mosaics and marble floors. But descend the staircase, and you’ll step into a 4th-century church. Go even lower, and you’ll find yourself in a 1st-century Roman house and pagan temple dedicated to Mithras.
This journey through three levels of history—Christian, early Christian, and pagan—feels like traveling in a time machine. It’s a must-see for anyone interested in the evolution of faith and architecture in Rome.
Near Piazza Barberini, the Capuchin Crypt offers a completely different kind of underground experience. Beneath the Church of Santa Maria della Concezione, the bones of nearly 4,000 Capuchin friars have been arranged into intricate designs—crosses, chandeliers, even floral patterns.
The message, inscribed on a plaque, is chilling yet profound: “What you are now, we once were; what we are now, you shall be.”
It’s both an artistic expression and a meditation on mortality—an unforgettable stop on any Rome Underground Tour.
Tucked near the Colosseum, the Case Romane del Celio (Roman Houses on the Caelian Hill) reveal beautifully preserved frescoes, mosaics, and hidden chapels beneath the Church of Santi Giovanni e Paolo. Once luxurious Roman homes, they were later adapted into Christian meeting spaces. Their intimate size and soft lighting make this one of the most atmospheric underground visits in Rome.
Joining a Rome’s Underground Tour is the best way to explore these hidden sites safely and meaningfully. Because many of them are active archaeological areas or sacred spaces, entry is often allowed only with a licensed guide.
Here’s what a typical underground tour might include:
Depending on the itinerary, some tours focus on the Appian Way catacombs, while others explore central Rome’s crypts like San Clemente or the Capuchin Crypt. Many also combine underground visits with above-ground landmarks, giving you a full picture of Rome’s evolution through time.
If you’re claustrophobic, note that most tunnels are well lit and ventilated, and tours typically last 1–2 hours underground. Comfortable shoes and a light jacket are recommended—temperatures stay around 15°C (59°F) year-round.
Rome’s underground is more than a collection of tombs and ruins—it’s a journey into the soul of the city. Each tunnel, fresco, and inscription tells a story of survival, faith, and transformation. While the monuments above celebrate imperial glory, the crypts below whisper tales of ordinary people, hidden communities, and silent devotion.
Visiting these spaces helps you understand Rome not just as an open-air museum, but as a living palimpsest, where every century left its mark above and below ground.
For history lovers, it’s a treasure hunt through time. For spiritual travelers, it’s a sacred pilgrimage. And for the curious, it’s an unforgettable reminder that in Rome, every step—up or down—leads to a new discovery.
The best way to experience Rome’s Underground is through a private guided tour that takes you beyond the surface, both literally and historically. With a professional archaeologist or local expert leading the way, you’ll uncover hidden tunnels, early Christian frescoes, and centuries-old burial chambers that most travelers never get to see.
Private tours allow you to move at your own pace, ask questions freely, and access restricted areas often closed to larger groups. It’s a personalized journey through the Eternal City’s most mysterious layers—perfect for history enthusiasts, families, or anyone who wants to see Rome from a different perspective.
