Beneath the streets of Rome lies a city most visitors never think to look for: hundreds of kilometres of underground tunnels, carved by hand nearly two thousand years ago, holding the remains of early Christians and some of the oldest surviving Christian art on Earth. Welcome to the Catacombs of San Callisto.
What Are the Catacombs of San Callisto?
Roman law forbade burials within the city walls, so early Christian communities carved their dead into the soft volcanic rock just outside Rome, beginning in the 2nd century AD. The Catacombs of San Callisto are the largest and most significant of these networks often called the “Little Vatican” because nine 3rd-century popes were buried here, alongside countless early Christian martyrs. The scale is genuinely staggering: roughly 20 kilometres of tunnels across four underground levels, lined with thousands of burial niches and faded frescoes that count among the earliest known Christian imagery in existence.
Are the Catacombs of Rome Worth Visiting?
Absolutely for the right traveller. If you’re drawn to Rome’s ancient and early Christian history, few experiences come close. The atmosphere underground is genuinely unlike anything else in the city: cool, silent, and centuries removed from the crowds above. The tunnels involve uneven stone steps and dim lighting in places, so the experience suits curious, comfortable walkers rather than those uneasy in enclosed spaces.
Our Catacomb Adventure Tour: San Callisto + the Appian Way
Our Catacomb Adventure Tour pairs San Callisto with a walk along the Appian Way (Via Appia Antica) the oldest and most famous Roman road, built in 312 BC and once the main route connecting Rome to the southern Empire. Walking sections of original Roman paving stones, still in place after more than two thousand years, is a remarkable way to bookend the underground experience with the world above.
