Map of Rome off the beaten path
18 Unknown Places in Rome
#1 Sciarra Gallery
The Galleria Sciarra is a true hidden gem from the late 19th century, originally designed as a shopping arcade. I first stumbled upon it during a school trip to Rome, and it took my breath away the moment I stepped inside. What makes it so remarkable is how unexpectedly beautiful it is, tucked away out of sight. This charming gallery is actually a courtyard, concealed within the walls of another building. It features a stunning glass roof that seems to stretch towards the sky, and it’s connected to the streets on both sides, inviting you to wander through and take in its enchanting atmosphere at your own pace.
What makes this place truly remarkable are the stunning Jugendstil murals that grace its walls. These colorful frescoes bring to life themes such as female virtues, courage, and devotion, creating an atmosphere that feels both timeless and inspiring. Originally designed as an exclusive gathering spot for the city’s elite, the gallery is now open to everyone, offering a quiet haven for those in the know. Just a short stroll from the Trevi Fountain, it’s surprisingly overlooked by most tourists, making it the perfect place to escape the hustle and bustle and enjoy a moment of peaceful beauty.

#2 Saint Stephen Round
Saint Stephen Round stands out as one of Rome’s most distinctive churches, thanks to its rare round shape, inspired by the Holy Sepulchre in Jerusalem. Built in the fifth century, it’s dedicated to Saint Stephen, the first Christian martyr. The church’s circular design and open central space create a unique and peaceful atmosphere, setting it apart from the more typical basilicas scattered across the city. This extraordinary layout not only gives the church a striking visual appeal but also enhances its sense of tranquility and timelessness, making it a truly remarkable place to visit.
Inside, you’ll find yourself face to face with some rather unsettling frescoes that depict the martyrdoms of saints. These 17th-century paintings are so vivid and detailed that they almost serve as a graphic, encyclopedic record of ancient torture methods. Luckily, during my visit with my 3-year-old daughter, a wedding ceremony was underway, so we didn’t spend much time lingering on the frescoes and were able to avoid focusing on the disturbing scenes.

#3 Baths of Caracalla
The Baths of Caracalla, built in the 3rd century AD under Emperor Caracalla, were once the largest and most impressive public baths in the ancient world. This vast complex could accommodate thousands of visitors and boasted an array of amenities, including baths of various temperatures, sports facilities, libraries, and lush gardens.
But these baths were much more than just places to cleanse the body—they served as vibrant social hubs where people came together to relax, chat, and engage in lively debates. With their sheer grandeur and cultural importance, the Baths of Caracalla played a central role in daily life in ancient Rome, offering not just physical relaxation but a space for communal interaction and intellectual exchange.
The remarkable ruins of the Baths of Caracalla today provide a striking window into the splendor of the ancient Roman bathhouse. If you’ve already visited the Roman Forum, you might think you’ve seen your fair share of beautiful ruins. However, you’ll likely be just as awestruck as I was by the towering arches and impressive remnants still standing here. As you explore, you’ll discover fragments of intricate mosaic floors and traces of the original marble decorations.
Despite being just a short walk from the Colosseum and the Forum, these baths attract surprisingly fewer visitors. This allowed us to enjoy a quiet, undisturbed experience, wandering through the grandeur of Ancient Rome. It was a refreshing change from the more crowded sites like the famous amphitheater and forum, offering a truly unique perspective on the city’s past.

#4 Santa Maria Sopra Minerva
Nestled next to the Pantheon, the Basilica of Santa Maria sopra Minerva is one of my absolute favorite spots in Rome. It stands out as one of the few Gothic-style churches in the city, and its stunning deep blue ceiling, speckled with golden stars, is truly one-of-a-kind. The church’s name alludes to the remains of a Roman temple that was once dedicated to the goddess Minerva, believed to have stood on this very site. However, in reality, the temple was located just a few meters away, and this space originally housed a different structure. The church we see today was built in the 13th century and is a rare example of Gothic architecture in a city more commonly associated with Renaissance and Baroque styles.
The church’s modest, almost plain exterior is a stark contrast to the opulence of its interior, where you’ll find intricate frescoes, stunning stained glass windows, and magnificent sculptures by some of the greatest artists, including Michelangelo. One of the church’s most important masterpieces is Michelangelo’s Christ the Redeemer, displayed next to the altar. The church is also the final resting place of Saint Catherine of Siena, adding to its spiritual significance.
Just outside, you’ll encounter one of Bernini’s most fascinating creations: an elephant sculpture, balancing an Egyptian obelisk on its back.


#5 The Keyhole of the Aventine Hill
I hesitated for a moment about whether to include this spot in my list of hidden gems in Rome. Once a quiet, undiscovered treasure, the photogenic keyhole now surprisingly had a full line of people during my visit in December 2024. Despite its newfound popularity, I still believe it’s a must-see gem you definitely shouldn’t miss.
On the Aventine Hill, you’ll discover one of Rome’s most captivating secrets: the keyhole at the Priory of the Knights of Malta. Though simple in design, this keyhole offers an extraordinary view of St. Peter’s Basilica, its iconic dome perfectly framed by a lush green hedge. The sight is so perfectly aligned that it almost feels as though it was crafted deliberately for this exact purpose. Just a short stroll from here, you can visit the nearby Santa Sabina and the Orange Garden, both offering breathtaking panoramic views of the city.
#6 Path of the Biscione
The Path of the Biscione is a narrow, covered alley tucked away near Campo de’ Fiori. This charming passage connects Piazza del Biscione with Piazza dei Satiri, offering a rare glimpse into medieval Rome. On the outside, it may appear unremarkable, but step inside and you’ll be greeted by stunning 16th-century frescoes adorning the vaulted ceiling. Though time has worn them, the faded artwork only enhances the passage’s sense of history and character. In one of the niches, you’ll find a statue of the Virgin Mary, which was once a popular stop for pilgrims in the 18th century, adding to the spiritual atmosphere of this hidden gem.
The once-hidden charm and mystery of the Passetto del Biscione have undoubtedly faded in recent years. In 2024, the alley captured widespread attention on Instagram when a Rome-based influencer shared a post about it. The video quickly went viral, sparking a surge of visitors—ranging from art lovers to tourists searching for the perfect, offbeat selfie spot. What was once a quiet, lesser-known treasure has now become a popular destination, as its secret allure has been revealed to the world.



#7 Capuchin Crypt
The Capuchin Crypt beneath the Church of Santa Maria della Concezione on Via Veneto stands as one of Rome’s most interesting sights. This 17th-century crypt is hauntingly decorated with the bones of over 4,000 Capuchin monks. Skulls, ribs, and other skeletal remains are meticulously arranged in elaborate geometric patterns across the walls and ceilings, creating a chilling yet strangely mesmerizing display.
These macabre arrangements were designed as a stark reminder of life’s fleeting nature and the importance of spirituality. Visitors are not permitted to take photos, ensuring the crypt’s solemn, contemplative atmosphere is preserved, allowing you to fully absorb the eerie beauty and profound message it conveys.
#8 Domus Area
The Domus Aurea, or Golden House of Nero, is an underground palace that once epitomized the extravagant tastes of Emperor Nero. After the devastating fire of Rome in 64 AD, Nero embarked on building this luxurious complex, featuring golden ceilings, stunning mosaics, and even artificial lakes. The palace stretched over a vast area, reflecting the emperor’s unrestrained opulence. However, following Nero’s death, his successors demolished much of it, seeing it as a symbol of his excess and decadence. Today, the ruins of this grandiose palace offer a captivating look into the splendor and ambition of one of Rome’s most controversial rulers.
Currently, visitors can explore the underground remnants of the Domus Aurea with a knowledgeable guide. The frescoes, still remarkably well-preserved, offer a breathtaking insight into the opulence of the palace and were a significant influence on Renaissance artists. Modern technology, including virtual reality, enhances the experience, allowing you to virtually step back in time and see how the Golden House once dazzled with its splendor.
Situated just a stone’s throw from the Colosseum, the palace isn’t open every day, so it’s wise to book tickets in advance, as they tend to sell out quickly. During my own visits to Rome, I found the Domus Aurea frequently closed for restoration, so it’s always a good idea to double-check online for up-to-date opening information before planning your visit.
#9 Barracco Museum
The Barracco Museum is a true hidden gem, tucked away on the lively Corso Vittorio Emanuele II, offering a captivating collection of classical art. What makes it even more delightful is that admission is completely free, allowing visitors to step into the world of ancient artistry without spending a penny. It’s the perfect destination for anyone looking to explore history and culture in a relaxed, accessible setting.
The Barracco Barracco Museum takes its name from Giovanni Barracco, a 19th-century aristocrat and avid collector of ancient art. In 1904, he generously donated his remarkable collection, which spans Egyptian, Mesopotamian, Greek, and Roman masterpieces, to the city of Rome.
The museum is housed in a charming Renaissance-era palazzo, and the building alone is worth the visit. Once inside, don’t forget to gaze up at the exquisite frescoes on the ceiling. And when you make your way to the top floor, take a moment to step out onto the lovely balcony, where you can enjoy a scenic view of the surrounding area.


#10 Nativity of the Garbage Collectors
You might not immediately associate Rome with Christmas, and we didn’t either—until recently. On our last visit in December, we found the city beautifully draped in holiday cheer. But there’s one special place where the Christmas spirit is alive and well all year long. The Presepe dei Netturbini is perhaps the most unique nativity scene in Rome, and it’s open for admiration throughout the entire year, not just during the holiday season.
The nativity scene was crafted by the city’s waste collectors, who used materials they come across in their daily work. This one-of-a-kind display is tucked away near the Vatican, in a space on Via dei Cavalleggeri. Its charming, resourceful creation makes it a true hidden gem that’s sure to capture your attention.
The nativity scene, created in 1972, is a remarkable handmade work of art crafted entirely from recycled materials like wood, metal, and glass. Every intricate detail, from the rustic houses to the bustling market stalls, has been carefully shaped with precision by the dedicated workers. What truly sets this nativity scene apart is that it not only captures the birth of Christ but also brings to life the daily rhythms of Bethlehem. While entry is free, donations are gratefully accepted and go towards sustaining this one-of-a-kind project for future generations.
#11 Church of Saint Ignatius of Loyola
Sant’Ignazio di Loyola is one of the most striking Baroque churches in Rome, built in the 17th century to honor Ignatius of Loyola, the founder of the Jesuit order. The church is particularly celebrated for its awe-inspiring ceiling fresco by Andrea Pozzo, a true work of art. This masterpiece creates a remarkable illusion of an open sky, with Ignatius and other Jesuits portrayed ascending toward the divine, as if reaching for the heavens. The artistry and grandeur of this church make it an unforgettable sight in the heart of Rome.
What was once a hidden gem is now anything but. To fully admire the stunning ceiling without craning your neck, a large mirror has been placed in the center of the church. This mirror gained viral fame on TikTok multiple times in 2024, catapulting the church to celebrity status. As a result, crowds of visitors now flock to Rome specifically for their perfect “mirror selfie.” There’s even a dedicated line for the mirror, and visitors must pay a fee to take their shot. While you can still photograph the ceiling or capture a picture of yourself with it, doing so without the mirror just isn’t part of the viral TikTok trend.
Many visitors rush off after snapping their selfies, which is a real shame. The ceiling and Baroque features of the church deserve much more time and attention. One truly remarkable detail is the painted “dome”—a brilliant trompe-l’oeil that masterfully creates the illusion of depth. With no funds available for an actual dome, Pozzo crafted this astonishingly realistic illusion, offering a breathtaking substitute that’s every bit as grand.


#12 Case Romane del Celio
If you’re eager to explore Roman antiquities beyond the usual tourist spots, I highly recommend seeking out this hidden gem. It wasn’t until my seventh visit to Rome that I discovered this incredible site, and I truly encourage you not to wait as long as I did. Nestled beneath the Basilica dei Santi Giovanni e Paolo on the Caelian Hill, you’ll find one of the city’s most captivating archaeological treasures: the Case Romane del Celio. This remarkable complex, with over twenty rooms, offers an exceptional and intimate look into the heart of ancient Rome, making it a must-visit for history enthusiasts.
In ancient times, a number of buildings on this site were brought together by a single owner, probably a wealthy family. The ground floor of the insula was transformed into an elegant residence, its rooms richly decorated with stunning frescoes. Many of these frescoes can still be admired today, showcasing intricate mythological scenes and decorative motifs that reflect the beauty and style of Roman art from that era.
In the 4th century AD, the complex was repurposed for a new use. According to tradition, the martyrs John and Paul once lived here during the reign of Emperor Julian the Apostate. It is believed that they were martyred and buried at this very site because of their Christian faith. In the 5th century, a basilica was built above what were thought to be their graves. However, the Case Romane remained hidden from view until the 19th century, when they were rediscovered by Father Germano di San Stanislao. While searching beneath the basilica for remnants of the early Christian martyrs, he made an astonishing find—an extensive network of rooms, adorned with stunning Roman frescoes, that had been concealed for centuries.


#13 Piccola Londra (Little London)
Nestled in the heart of Rome, there’s a street that feels more like something you’d find in England: Piccola Londra. This charming, hidden neighborhood was designed in the early 20th century by an architect who drew inspiration from the serene beauty of English garden suburbs. The street is lined with houses that boast colorful facades, quaint front gardens, and delicate wrought-iron fences. It’s a striking departure from the more classical Roman streets, offering a delightful contrast to the city’s historic charm.
Piccola Londra was originally conceived as an exclusive residential enclave for the upper middle class, and even today, it maintains a tranquil, almost village-like charm. This quiet, residential street offers a welcome escape from the more hectic areas of Rome. Situated in the Flaminio district, not far from the MAXXI Museum of Contemporary Art, it’s just enough outside the city center to feel serene, yet still conveniently close to the heart of Rome.
#14 Tiber-Island
Tiber Island is a teardrop-shaped gem nestled in the heart of the Tiber River, a landmark that has been integral to Rome’s story for centuries. Its religious significance dates back to the third century BC, when a temple was constructed in honor of Aesculapius, the god of healing. This ancient connection to health and medicine still lingers today, as the island is home to the Fatebenefratelli Hospital and the Basilica di San Bartolomeo, both standing as symbols of the island’s enduring legacy.
Tiber Island can be reached by two historic bridges: the Ponte Fabricio, which dates back to 62 BC and remains remarkably well-preserved, and the Ponte Cestio, linking the island to the charming neighborhood of Trastevere. In the summertime, the island takes on a lively, almost magical atmosphere, transforming into a buzzing cultural hotspot. Expect open-air film screenings, bustling markets, and live music, all contributing to the island’s vibrant energy.

#15 Marcello Theatre
The Marcello Theatre is one of Rome’s oldest and most well-preserved theaters, originally commissioned by Julius Caesar and completed by Emperor Augustus in 13 BC. With its impressive capacity to seat around fifteen thousand spectators, this grand theater once hosted a wide array of cultural events, from dramatic plays to musical performances. It played a central role in the vibrant social and cultural life of ancient Rome, standing as a testament to the city’s rich entertainment heritage
What makes the Marcello Theatre truly captivating is how it was repurposed long after the fall of the Roman Empire. In the Middle Ages, the upper levels were transformed into a fortress, and by the 16th century, residential buildings were constructed on its upper tiers—some of which still stand today. Situated in a peaceful area not far from the iconic Colosseum, the theater is encircled by ancient columns and the remnants of old temples. While you can’t step inside the theater itself, it’s well worth taking a leisurely walk around it, allowing your imagination to transport you back two thousand years to envision its grandeur in ancient times
#16 Cat Forum Largo di Torre Argentina
Largo di Torre Argentina is a captivating spot where history and a love for animals beautifully intersect. The square is home to the remnants of four ancient temples, dating back to the 3rd and 2nd centuries BC. Though their exact names and functions remain a mystery, these temples are among the oldest Roman structures still visible in the city. Beyond its archaeological allure, the square holds significant historical weight, as it was the site where Julius Caesar met his tragic end in 44 BC.
What truly sets Largo di Torre Argentina apart is its thriving colony of cats, who have made this historic site their home. Amidst the ancient ruins, dozens of felines wander freely, cared for by passionate volunteers. Beneath the square, you’ll find an underground shelter that offers a safe haven for Rome’s stray cats. If you’re moved by their story, you can show your support by making a donation or even adopting a cat from afar. Conveniently located just a short walk from the Pantheon, this square offers a unique blend of history, culture, and compassion.
#17 Alchemical Gate in Piazza Vittorio Emanuele II
The Porta Alchemica, or Alchemist’s Gate, is a captivating relic from the 17th century. Originally part of the villa owned by Massimiliano Palombara, a marquis famous for his deep fascination with alchemy, the gate stands as a symbol of the mystical and enigmatic world he sought to understand. This intriguing piece of history invites visitors to step into a realm where science, magic, and mystery once intertwined.
Legend has it that Palombara once welcomed an alchemist who claimed to have unlocked the secret of the Philosopher’s Stone. By morning, however, the mysterious visitor had vanished without a trace, leaving behind only a series of strange symbols. Believing these cryptic markings, along with accompanying Latin inscriptions, held the key to the mysteries of alchemy, Palombara had them etched into the gate. Currently, this fascinating gate stands in the park at Piazza Vittorio Emanuele II, drawing curious visitors captivated by its enigmatic past and the secrets it may still conceal.
#18 Napoleonic Museum
The Napoleonic Museum provides a fascinating insight into the life of Napoleon Bonaparte and his family. Nestled on Via di Ripetta, just a short stroll from Piazza del Popolo, this charming museum is housed in a beautifully preserved 19th-century palazzo, offering visitors a blend of history and elegance.
The collection, generously donated in 1927 by Count Giuseppe Primoli—a descendant of Napoleon’s brother Lucien—offers a captivating glimpse into the world of the Bonaparte family. It includes a rich array of personal belongings, paintings, furniture, and costumes that once belonged to this iconic family. Each item carries a unique story, reflecting their dramatic journey from exile to life at the height of royal court society. Among the collection’s treasures are stunning portraits of Napoleon and his family, intricately crafted jewelry, and a selection of exquisite French Empire-style furniture. These objects provide a window into the lavish, yet often turbulent, lives of one of history’s most powerful and influential families.
What makes this museum special is its charming, intimate atmosphere. We were pleasantly surprised to stumble upon a palace brimming with Napoleon artifacts in a city like Rome. Admission is completely free.


#19 Colonna Gallery
The Galleria Colonna is one of Rome’s hidden gems. This captivating museum provides a rare glimpse into the life of the noble Colonna family, who have made this grand residence their home since the 15th century. Rich in history and elegance, it invites visitors to explore the legacy of a family whose influence has spanned centuries.
The crown jewel of the Galleria Colonna is the Grand Hall, an opulent space graced with marble columns, golden embellishments, and ceiling frescoes that recall the grandeur of the Palace of Versailles. The art collection is equally remarkable, showcasing works by renowned masters like Carracci, Tintoretto, and Bronzino. Equally captivating is the balcony, which offers a stunning panorama of the ancient ruins of the Roman Forum, creating a perfect blend of art, history, and breathtaking views.
The Colonna family still occupies part of the palace, offering visitors a rare glimpse into the world of aristocracy, as though they are stepping behind the velvet curtains of history. Since the gallery is only open on Saturdays or by appointment, it’s a good idea to secure your ticket in advance to guarantee entry and make the most of this exclusive experience.
#20 Doria Pamphilj Gallery
The Galleria Doria Pamphilj is a true hidden gem nestled in the heart of Rome, making it an essential stop for any art enthusiast. Situated on the lively Via del Corso, the moment you step inside, you’re transported into a completely different world. The museum offers a serene retreat from the hustle and bustle of the city, inviting visitors to immerse themselves in its rich history and stunning collection.
The 16th-century palace, still owned by the noble Doria Pamphilj family, is a living testament to history and grandeur. Its collection boasts masterpieces by some of the greatest artists in history, including Caravaggio, Velázquez, and Titian. Among its most celebrated works is Velázquez’s iconic portrait of Pope Innocent X, regarded as one of the most striking and powerful papal portraits ever painted. The rooms are lavishly decorated with mirrors, marble floors, and stunning ceiling frescoes, creating an atmosphere that makes visitors feel as though they are strolling through the halls of a royal palace.
An audio guide, narrated by a member of the family, weaves in personal anecdotes that add an extra layer of charm to the experience. With the museum open daily, visitors have the opportunity to explore its remarkable collection at their leisure, fully immersing themselves in its history and beauty.
#21 Altemps Palace
Palazzo Altemps is a stunning example of elegance, nestled just steps away from Piazza Navona. This 15th-century palace is part of the National Roman Museum and is renowned for its impressive collection of ancient sculptures. Yet, the true marvel lies in the building itself. A masterpiece of Renaissance architecture, it boasts beautifully detailed frescoes, sweeping marble staircases, and intricate ceilings—all of which capture the opulence and grandeur of the era.
The collection boasts an impressive array of Greek and Roman sculptures, many of which once belonged to prestigious noble families like the Ludovisi family. Among its most celebrated treasures are the renowned Ludovisi Throne and the powerful statue of the Dying Gaul, both stunning masterpieces from classical antiquity. The museum itself is compact yet thoughtfully arranged, making it a pleasure to explore.
Admission is included with the combined ticket for the National Roman Museum, offering visitors a seamless opportunity to visit other historic landmarks, such as the magnificent Baths of Diocletian.
#22 Palazzo della Sapienza
The Palazzo della Sapienza is a historic gem that has long been the beating heart of the University of Rome. Construction began in the 16th century and was completed in the 17th century, when the renowned architect Francesco Borromini added the breathtaking Sant’Ivo alla Sapienza church to the complex. This church is a true architectural marvel, famous for its distinctive spiral-shaped dome, which brilliantly reflects Borromini’s innovative design style. While the church welcomes visitors year-round, the rest of the complex is generally only open on special occasions, offering a rare glimpse into its rich history.
#23 Saint Martin at the Mountains
Saint Martin at the Mountains is a hidden gem nestled on the Esquiline Hill, one of Rome’s oldest and most storied hills. The church itself dates back to the 4th century and has been lovingly renovated over the centuries, preserving its rich history. Yet, the real marvel lies beneath the church, where layers of history are tucked away, offering a fascinating glimpse into the past for those who venture below.
A staircase tucked behind the altar leads you to a fascinating crypt that was once part of a grand Roman bath complex. As time passed and the baths fell into disrepair, the space was repurposed first as a bustling covered marketplace, and later as a Christian place of worship. Here, history unfolds before your eyes in layers, with the original mosaics still covering the crypt’s floor, providing a direct and tangible link to the past. Best of all, admission is completely free, and because the location is so hidden, you can often wander through its quiet halls in peaceful solitude.
