If you’re visiting Rome and want to see beyond the surface, the Trevi Fountain Underground Small Group Tour offers a fascinating peek into the city’s lesser-known layers. While most visitors toss coins into the famous fountain and snap photos, this tour invites you beneath the surface to explore the ancient aqueducts and archaeological remains hidden beneath the bustling streets.
What we love about this experience is how it combines the iconic beauty of the Trevi Fountain with a taste of Roman engineering and history that isn’t on every guidebook. You get to walk through underground passages and see actual remains of aqueducts built almost two thousand years ago. Also, the small-group format makes for a more intimate, engaging experience—perfect if you prefer your tours to be personal rather than crowded.
One thing to consider is that the tour lasts only 45 minutes, so it’s quite focused. If you’re looking for a deep dive into Roman history or extensive sightseeing, this might feel a bit brief. Plus, it’s not suitable for wheelchair users, so if accessibility is a concern, you’ll want to explore other options. But overall, this tour suits travelers who appreciate history, love unique experiences, and want a more exclusive look at Rome’s underground wonders.

What the Tour Offers: A Closer Look at Rome’s Underground

Rome’s streets are like layers of history, each telling stories of different eras. This tour zeroes in on a particularly captivating aspect—the underground remains of the aqueducts that supplied water to the city. These aqueducts, especially the Aqua Virgo, have romantic legends attached to them, like the story of Roman soldiers led to a spring by a young woman, giving the aqueduct its poetic name, which translates to “pure water.”
The tour starts at Piazza dei Crociferi, a small yet lively square just a short walk from the Trevi Fountain. Here, the guide with the “Rome with Silvia” sign greets you, ready to lead you into the underground world of ancient Rome. It’s worth noting that the meeting point is outside the archaeological site itself, so don’t wait there—look for your guide nearby.
Exploring Vicus Caprarius
Once underground, you’ll visit Vicus Caprarius, also known as “The City of Water.” This archaeological site is a treasure trove of remains from Rome’s past, discovered during renovation works in 1999. It became accessible to the public in 2004 and provides a tangible connection to Roman engineering.
Here, you’ll see the remains of one of the 11 aqueducts, including the monumental water tank built under Emperor Hadrian, which was part of the system to distribute water across the city. The site also includes parts of medieval houses and a domus from the Imperial era, giving a layered perspective of Rome’s urban evolution.
The guide will explain the significance of these remains, highlighting how vital water was for the city’s survival and prosperity. Expect to hear stories about the engineering techniques used and how the aqueducts were the lifeblood of ancient Rome.
The Trevi Fountain Photo Stop
After exploring underground, you’ll emerge at the famous Trevi Fountain for a quick photo session and a chance to appreciate its stunning Baroque design. While the tour itself doesn’t go beneath the fountain, this is a perfect moment to capture some memorable shots and listen to stories about its history and cultural significance.
Some reviews mention that the 45-minute duration might feel a bit brief, especially if you’re eager to spend more time absorbing the sights. But considering the focus on underground remains, it’s a good snapshot of Rome’s water infrastructure.
