1. Galleria Sciarra
Hidden steps from the Trevi Fountain’s tourist crush, this Art Nouveau courtyard delivers pure Instagram gold without the crowds.
Built between 1885-1890 as a shopping mall for the wealthy Sciarra family, the four-story passageway never fulfilled its commercial purpose, eventually bankrupting its aristocratic owner.
What remains is a breathtaking celebration of womanhood – every inch of wall space covered in vibrant frescoes by Giuseppe Cellini depicting females in various life stages.
2. Capuchin Crypt of Santa Maria della Concezione
Beneath the unassuming church of Santa Maria della Concezione lurks a subterranean art gallery where the medium is human bones.
This ossuary features six rooms where the remains of 4,000 Capuchin monks have been arranged into elaborate decorative patterns, chandeliers, and even full skeletal displays.
Far from morbid, the crypt serves as a memento mori – a reminder that life is fleeting.

3. Catacombs of St. Callixtus
Twenty meters below Rome’s surface stretches a labyrinthine necropolis that once served as the official burial ground for the early Christian Church.
The Catacombs of St. Callixtus sprawl across 20 kilometers of tunnels carved into soft tufa rock, housing the remains of 16 popes and approximately 500,000 Christians.
Located along the historic Appian Way, these catacombs offer a haunting glimpse into Rome’s underground history that feels worlds away from the tourist-packed Forum above.
4. Park of the Aqueducts (Parco degli Acquedotti)
Just beyond Rome’s bustling center, 240 hectares of green space showcase the engineering marvels that powered ancient Rome.
This sprawling park houses the remains of six different aqueducts, including the remarkably preserved Aqua Claudia with its impressive arched structures commissioned by Emperor Caligula in 38 CE78.
Once neglected and occupied by slums in the 1950s, the park has been reclaimed as a verdant retreat where locals jog beneath 2,000-year-old monuments.

5. Domus Aurea (Nero’s Golden House)
Hidden beneath modern Rome lies Emperor Nero’s 300-room pleasure palace that once sprawled across 200 hectares.
After Rome’s devastating fire in 64 CE, the emperor constructed this opulent complex featuring walls adorned with gemstones, ivory, and gold leaf.
The palace boasted intricate water features and even a spinning dome that showered guests with perfumed rose petals12.
Today, visitors can explore the excavated portions on guided weekend tours. For the full imperial experience, opt for tours with VR glasses that digitally reconstruct the palace’s original splendor.
6. Catacombs of Santa Priscilla
Nicknamed the “Queen of the Catacombs,” this underground labyrinth stretches over seven miles beneath Rome’s Via Salaria, making it one of the city’s most extensive burial networks.
Dating from the late 2nd to 5th centuries, these tunnels house thousands of early Christian tombs, including seven popes and countless martyrs.
The star attractions? Ancient frescoes depicting Biblical scenes with some of Christianity’s earliest female figures.

7. Orange Trees Garden (Giardino degli Aranci)
Perched atop the Aventine Hill, this dreamy orange grove delivers Rome’s most swoon-worthy panorama without the tourist hordes.
The 8,000-square-meter park sits on ancient fortress ruins, where stone pines tower cathedral-like over walkways lined with citrus trees supposedly imported from Spain.
Locals know this spot delivers pure magic at sunset – bring wine, pizza, and a blanket for the ultimate Roman picnic as the sun dips behind St. Peter’s dome.
8. Basilica of Santa Sabina
Rome’s oldest surviving basilica sits quietly on the Aventine Hill next to the Orange Garden, preserving its original 5th-century architectural style without later baroque embellishments.
Built between 422-432 AD on the site where Roman matron Sabina was beheaded for converting to Christianity, this church delivers ancient Rome without the crowds.
The real showstopper? Cypress wood doors from 430-432 AD featuring the world’s first publicly displayed crucifixion scene.

9. Baths of Diocletian
Once Rome’s largest imperial bathing complex, these massive ruins showcase ancient engineering prowess on a jaw-dropping scale.
Commissioned by Emperor Maximian in 298 AD to honor co-emperor Diocletian, the baths could accommodate 3,000 people simultaneously across their 376×361-meter footprint.
The remaining halls now house part of the National Roman Museum, where ancient statues and artifacts reveal daily life in imperial Rome.
10. Our Lady of the Conception of the Capuchins
This unassuming 17th-century church on Via Veneto hides Rome’s most macabre masterpiece beneath its modest sanctuary.
Commissioned by Pope Urban VIII and designed by Antonio Casoni, it became the first Roman church dedicated to the Immaculate Conception when completed in 1631.
But the real showstopper lurks below – a crypt where the bones of 4,000 Capuchin friars who died between 1528 and 1870 have been artistically arranged into six pocket-sized chapels.

11. St. Clement Basilica (Basilica San Clemente)
St. Clement Basilica is an unassuming church that stacks three distinct eras in one spot – a current 12th-century basilica sitting atop a 4th-century church, which itself perches on 1st-century Roman ruins.
The gold mosaics in the apse dazzle with Byzantine flair, but the real magic happens when you descend underground.
There, ancient frescoes tell stories in early Medieval vernacular, while deeper still, a shadowy Mithraeum temple reveals where Roman men once worshipped in secret.
12. Isola Tiberina (Tiber Island)
Rome’s tiniest inhabited island floats in the Tiber like a stone boat – literally, as ancient Romans sculpted its banks into a ship shape to honor a legendary healing snake.
At just 270 meters long and 67 meters wide, this compact slice of Roman history connects Trastevere with the Jewish Ghetto via two ancient bridges.
According to legend, the island formed when angry Romans tossed the hated King Tarquin’s wheat into the river.

13. Palazzo Massimo alle Terme
Across from Rome’s main train station sits a Neo-Renaissance palace housing ancient treasures that rival the Vatican’s collection without the crushing crowds.
This branch of the National Roman Museum spans four floors of jaw-dropping artifacts, but the second-floor frescoes steal the show.
Don’t miss the basement’s glittering collection of Roman jewelry – golden snake armlets and precious hair nets that once adorned wealthy Roman ladies.
14. Basilica di San Pietro in Vincoli
This understated 5th-century church houses two treasures worth the short walk from the Colosseum.
Under the main altar lies a bronze and crystal reliquary containing what tradition holds are the actual chains that bound St. Peter in Jerusalem and Rome.
But most visitors come for Michelangelo’s commanding “Moses” sculpture, the centerpiece of Pope Julius II’s unfinished tomb.
Originally planned as a massive 40-foot monument for St. Peter’s Basilica with numerous statues, the project was abandoned when Julius died, leaving only Moses and two flanking figures completed.

15. Aventine Hill and Knights of Malta Keyhole
The Aventine Hill keyhole might be the world’s most exclusive peephole – it lets you spy on three countries simultaneously!
Located at Piazza dei Cavalieri di Malta 3, this unassuming keyhole in a green door offers a perfectly framed view of St. Peter’s Dome through a tunnel of manicured hedges.
You’ll stand in Italy, peer through the sovereign territory of the Knights of Malta, and gaze directly at Vatican City.
