A unique experience in the secret heart of the Eternal City
Beneath the Trevi Fountain — one of Rome’s most iconic landmarks — lies an ancient, surprising and still-living world.
“Hidden Rome: Journey into the Underground of the Trevi Fountain” is a special guided tour that takes visitors below street level to discover water channels, archaeological remains and stories flowing invisibly beneath the modern city.
A fascinating experience, perfect for lovers of archaeology, history and immersive cultural tours.
The charm of water: the true protagonist of the tour
Water is the guiding thread of the entire experience.
As a vital element for Rome since antiquity, the water of the Aqua Virgo aqueduct still feeds the Trevi Fountain and the ancient underground cisterns.
During the visit, a licensed guide leads participants through:
- the hidden workings of the Trevi Fountain
- Roman hydraulic structures still functioning today
- the archaeological remains of Vicus Caprarius, the famous City of Water
- an ancient Roman district brought back to light, with rooms, basins and well-preserved artifacts
A true journey through time, blending engineering, history and wonder.
