While millions visit the famous landmarks above ground, few realize that another city exists underneath — one filled with secrets from the Roman Empire, early Christianity, and medieval times.
The lost underground tunnels of Rome have fascinated archaeologists, historians, and travelers for centuries. Some were used as escape routes, others as burial chambers, some still remain unexplored today.

Ancient Roman Catacombs
Among the most famous underground tunnels are the Roman catacombs. These vast burial networks were created between the 2nd and 5th centuries AD.
The best-known catacombs include:
- Catacombs of San Callisto
- Catacombs of San Sebastiano
- Catacombs of Priscilla
These underground labyrinths remain one of Rome’s most mysterious attractions.
The Underground Aqueducts
Rome’s underground tunnels also include ancient aqueduct systems that once supplied water to over a million residents. These engineering masterpieces transported fresh water from distant mountains into public baths, fountains, and homes. Some underground channels are still functional today.
The Romans built these tunnels with remarkable precision, proving why Roman engineering remains admired worldwide.
Why So Many Tunnels Were Lost
Many underground tunnels disappeared due to centuries of flooding, collapsed structures, and urban expansion. As Rome evolved, old buildings were buried and forgotten. New roads and churches covered ancient entrances, leaving entire sections hidden beneath modern neighborhoods.
In some cases, authorities sealed tunnels for safety reasons after discovering unstable passageways.
