Are you looking for hidden gems in Rome? Here are some unique experiences you won’t want to miss!
In addition to our top recommendation, we’ll share other hidden places in Rome that we discovered during our visit.
But let’s start with our favorite!
Our Favorite Hidden Gem in Rome
The Trevi Fountain is one of Rome’s most iconic sights. Just around the corner from this famous landmark lies a hidden spot we explored during a guided tour.
Modern Rome was built upon ancient ruins and structures, and that includes the area surrounding the famous Fontana di Trevi.
After sharing our Rome tips for first-time visitors, including a self-guided walking tour in Rome, itineraries for seeing Rome in one day, Rome in 2 days, and Rome in three days, or the worst time to visit Rome and more helpful tips, we want to share our favorite hidden gems of the Eternal City.
Only a few feet away from the Trevi fountain, you’ll find one of Rome’s best-kept secrets:
Underground Tour of the City of Water at Trevi Fountain
The tour’s highlights include the Trevi Fountain and the Citta’ dell’Aqua (City of Water), also known as Vicus Caprarius.
The tour starts next to the Trevi Fountain and lasts approximately 40 minutes.
> TREVI FOUNTAIN AND UNDERGROUND TOUR
While thousands visit the Trevi Fountain daily for photos or to to toss in a coin, few know its origins or the fascinating stories behind it.
On this tour, you’ll learn how the Trevi Fountain got its name, understand the meaning behind its statues and symbols, and find out why it was built into a building’s facade.
These insights, along with fun facts and stories, made this tour a memorable highlight for us.
Afterward, we explored an archaeological treasure in central Rome just around the corner.

The Discovery of the Citta’ dell’Aqua
The Citta’ dell’Aqua was found by chance during the construction of a movie theater.
Nearly 30 feet (9 meters) underground, you’ll find remnants of walls, corridors, and residential buildings that once served as living spaces, storage areas, and a water cistern.
The tour explains ancient Roman life and the aqueduct systems, some of which still bring water into homes today.
You’ll also find exhibits featuring coins and other artifacts from that era.
Although the site is relatively small, this tour of the Trevi Fountain and ancient ruins below Rome is truly a hidden gem.
It’s a refreshing break from the crowded city streets, a cool escape from the heat, or a great activity if you experience a rainy day in Rome!
More Off The Beaten Path Things To See in Rome
After seeing Rome’s top attractions—like the Colosseum, Roman Forum, Spanish Steps, and St. Peter’s Basilica in the Vatican—these lesser-known spots will make your visit even more memorable:
Moses Fountain
The Moses fountain is a stunning and lesser-known fountain in Rome.
Just a short walk from the Repubblica metro station, the Baroque-style Fontana dell’Acqua Felice (Moses Fountain) was built in the late 17th century.
It’s near the Santa Maria della Vittoria Church and the luxury St. Regis Hotel.
Temple of Hadrian and Neapolitan Coffee
Between the Pantheon and Trevi Fountain, Piazza di Pietra is home to the Temple of Hadrian, with its facade and eleven columns still standing.
Built in 145 AD, the temple’s facade and eleven columns are still visible today. For us, it should be included in every Rome bucket list.
For a fantastic view of the temple’s facade and piazza, stop by Gran Caffè La Caffettiera, where you can also enjoy a traditional Neapolitan coffee brewed in a unique copper pot for two.
Surprisingly smooth and mild, it’s a refreshing option even for those who find Italian espresso too strong like me.
Normally, Italian espresso gives me shivers and a racing heart.
The Cestius-Pyramid
If you’re heading to the Aventine Keyhole (Knights of Malta Keyhole), which offers one of the best views in Rome, take a quick detour at the Piramide metro station.
Here, you’ll find the Pyramid of Cestius, a fascinating Roman burial monument with a distinctly Egyptian style—a unique photo spot!
Centro Del Colonnato at St. Peter’s Square
The Centro Del Colonnato is a special vantage point in the middle of St. Peter’s Square in Vatican City.
The 50-foot-high columns (15 meters), designed by Bernini, create an optical illusion: from specific points, the columns align in just one row.
Designed by Bernini, these 284 columns were built in four rows, and there are two special points around the square’s obelisk where the rear columns seem to disappear, leaving just one row visible.
It’s a little-known architectural marvel! Learn more about it in our visiting Vatican City guide.
The Cat Sanctuary At Largo Di Torre Argentina
Largo di Torre Argentina is an area with ruins of ancient buildings, famously known as the site where Caesar was murdered.
Today, cats roam these historic grounds, and a cat sanctuary is just beside the ancient area.
When visiting Largo di Torre Argentina, keep an eye out for the cats!
