When it comes to sightseeing in Rome, fountains and aqueducts are often at the top of travelers’ wish lists. This tour offers a fascinating look at both the celebrated and the lesser-known water features that give the Eternal City its charm. We’re reviewing a 2-hour guided walk that combines the well-known Trevi Fountain with some of Rome’s underground water systems, including the surprisingly captivating Vicus Caprarius, beneath the Trevi.
Two things stand out about this experience: first, the expert guidance that brings the stories behind each fountain to life, and second, the chance to see hidden archaeological features that most visitors never encounter. The main drawback? The overall time is short, so if you’re a fountain fanatic or history buff, you might wish for a longer, more in-depth exploration.
This tour is ideal for travelers who love architecture, history, and a bit of adventure—especially those who enjoy uncovering Rome’s lesser-known stories alongside its famous monuments.

Discovering the Waterworks of Rome: An Introduction

This walking tour is a clever way to blend the celebrated beauty of Rome’s fountains with the hidden engineering marvels beneath the streets. As most visitors admire the Trevi Fountain from afar, few realize the city’s water supply system is just as intriguing as its sculptures and architecture. The tour’s focus on Vicus Caprarius, an underground aqueduct and water city, offers a fresh perspective.
What we love about this tour is how knowledgeable guides bring to life the stories behind the fountains, making the experience both educational and playful. Plus, the inclusion of stunning sights like Bernini’s Fountain of the Four Rivers in Piazza Navona elevates the experience from simple sightseeing to a deeper appreciation of Rome’s artistic achievements.
One potential drawback is the short length—just about two hours—so it’s best suited for those who want a quick overview rather than an exhaustive exploration. If you’re after a comprehensive deep dive into Rome’s water infrastructure, this might only be the starting point.
This experience suits travelers who enjoy history, art, and discovering roman engineering marvels, especially if they prefer guided tours that keep things lively and informative.

Exploring the Itinerary: What You’ll See and Why It Matters

Start at Piazza Venezia and the Altare della Patria
The tour begins in the bustling Piazza Venezia, dominated by the Altare della Patria. This imposing monument, built between 1885 and 1911, celebrates Italy’s unification and its heroes. While this is a landmark many travelers see from a distance, our guide will explain the layers of history embedded in its marble and symbolism.
You’ll appreciate how this monument is a modern addition compared to Rome’s ancient ruins, yet it’s integral to the city’s identity. It’s a good starting point that sets the tone for understanding Rome’s layered history.
Fontana del Tirreno and the Sea Fountains
Next, we pause at the Fountains of the Tyrrhenian and Adriatic Seas, designed by Giuseppe Sacconi. These symmetrical fountains symbolize Italy’s maritime identity—an important reminder of Rome’s connection to the seas that once defined its empire. Here, you get a glimpse of Renaissance craftsmanship combined with 20th-century grandeur.
Fontana delle Tartarughe: Playful Renaissance Charm
We then stroll to the Turtle Fountain, dating from the late 1500s. Designed by Giacomo della Porta, its playful bronze turtles and dolphins evoke a sense of whimsy that still delights visitors today. The fountain’s craftsmanship highlights the Renaissance’s love of intricate detail and lively design, making it more than just a water feature; it’s a piece of art that captures the joy of the period.

Bernini’s mastery is clear in how he captures the movement and personality of each river’s element, making it a true sculpture in motion. The fountain’s grand scale and mythic themes are a testament to Baroque artistry.
The Trevi Fountain: The Star of Rome
The tour’s most famous stop is, of course, the Trevi Fountain. Built between 1732 and 1762, it’s an icon of Baroque creativity. You’ll learn about how it connects to Rome’s ancient Acqua Vergine aqueduct, an engineering feat that still supplies water today. The story of the contest to design it and Nicola Salvi’s winning vision makes the fountain’s grandeur even more meaningful.
The tradition of tossing coins into the fountain, to ensure your return to Rome, is a charming ritual that many visitors partake in. Expect a lively atmosphere here, and your guide will share tips on how to enjoy it without getting caught in the crowd.
Vicus Caprarius: Hidden Water City Beneath Rome
Finally, we descend into Vicus Caprarius, also called the City of Water. Discovered in 1999 beneath a cinema, this archaeological site reveals the remains of an ancient Roman water tank connected to the Vergine aqueduct. Exploring this underground space gives a tangible sense of how Romans managed their water supply—something that was essential to the city’s growth and comfort.
This part of the tour is especially captivating because it’s off the beaten path and offers a glimpse into Rome’s engineering prowess that most travelers never see. The site is small but packed with history, and the guide will explain its role in the ancient water infrastructure.
