About this tour
This 2.5-hour private tour pairs Rome's most photographed fountain with a rare descent into the ancient aqueduct system beneath it. You'll explore Trevi Fountain's baroque sculptures—Oceanus, seahorses, tritons—then venture underground to walk through the Aqua Vergine, the sole Roman aqueduct still functioning today. Your guide reveals how this 2000-year-old engineering feat supplies water to fountains across the city, including those in Navona Square. A chance to see Rome's infrastructure the way Romans do, not just its surface.

- Baroque carvings and mythology at Trevi Fountain up close
- Walk through functioning 2000-year-old Roman aqueduct tunnels

What to expect
You'll start at Trevi Fountain, where your guide decodes the sculptural programme—Oceanus commanding the waters, mythological creatures symbolising the sea's power. Then you descend into the Aqua Vergine's subterranean sections, where stone channels and chambers reveal how Romans moved water across kilometres without pumps. The underground is cool, shadowed, and tactile—you're standing in functioning infrastructure, not a museum piece. Your guide contextualises what you're seeing in real time, connecting ancient Roman ambition to modern plumbing.
Good to know
Wear comfortable shoes suitable for uneven stone surfaces underground. The tunnels maintain a steady cool temperature. Public transport links nearby make arrival straightforward. Tour suits all fitness levels, though you'll do some light climbing and walking on ancient flooring.
