Exploring Rome’s St. Mary Major Basilica: Dome Access & Underground Tour Review

When it comes to Rome’s grand churches, few hold the same level of significance and beauty as Santa Maria Maggiore. This tour, offered by GOOD ITALY LTD, promises a deep dive into one of the city’s most revered religious sites, combining art, history, and breathtaking views in just under two hours. Whether you’re a history buff, a lover of art, or simply seeking a meaningful experience during your Roman adventure, this tour offers a well-rounded peek into the basilica’s soul.
What makes this experience stand out? First, the chance to visit the dome’s viewing platform—a rarity and an absolute must for panoramic city vistas. Second, the underground exploration reveals layers of history beneath the basilica, including parts of the original 4th-century structure. Lastly, the expert guide, often praised for their thorough knowledge, ensures each stop is engaging and informative. One thing to consider: the underground tour involves stairs and isn’t suited for all mobility levels. For those willing to navigate stairs and eager to uncover hidden facets of Rome’s sacred architecture, this tour offers serious value.
This experience is especially suited for travelers who want more than just a cursory visit. If you’re interested in art, religious symbolism, and exclusive access, and are okay with the time commitment of around 1 to 1.5 hours, it’s a solid choice. Families with children over 7 who don’t have mobility issues will also find it rewarding. However, those with mobility impairments or large luggage should consider alternative options, as stairs and security checks are part of the process.

An In-Depth Look at the Tour Experience

How the Tour Is Structured
You can choose between two main options, each designed to maximize your understanding of the basilica’s history and beauty. The first is a standard basilica tour, perfect for those who want to appreciate the mosaics, relics, and papal history while wandering through the main space. The second adds a dome visit and underground exploration, offering panoramic views and secret layers beneath the church.
Dome Access: Views and Impressions
Starting at 10 AM, the dome access is a highlight praised by many. The climb—not overly strenuous—offers sweeping views of Rome’s rooftops and iconic landmarks. One reviewer, Rachel from the UK, called it “really interesting,” noting the perspective from above was “fascinating” and a chance to see the city in a new light. It’s worth noting that this access is exclusive and involves waiting for your turn, so arriving on time and prepared for a brief ascent is key.
More Great Thing To Do NearbyUnderground Tour: Unearthing Ancient Rome
At 11:30 AM, the underground portion begins. This part is reserved for those who are comfortable descending stairs and exploring dimly lit spaces. The underground tour provides a glimpse into the earliest phases of the basilica’s history—the remains of the original 4th-century structure. Visitors pass through archaeological excavations and underground corridors, offering a tangible connection to the past.
A tip from one reviewer: “The underground part does not include Holy Door access,” so if that’s on your must-see list, plan accordingly. The underground environment isn’t suitable for children under 7 or those with mobility difficulties because of stairs and uneven surfaces.

Additional Hidden Gems
The tour grants access to the Loggia delle Benedizioni, the Hall of the Popes, and Bernini’s Staircase, which are usually closed to the public. These spaces let you see the church’s art and architecture from unique angles—adding layers of understanding to your visit.
The Art and Symbols
We loved how the guide explained the basilica’s mosaics and Marian relics, revealing their symbolism and historical significance. The Salus Populi Romani icon, for example, is not only a revered image but also an important symbol for Pope Francis, especially during Jubilee 2025.
Price and Value
At $41 per person, the tour is competitively priced given the depth of access and expert guidance. The inclusion of skip-the-line entry and access to usually restricted areas adds to the value. For anyone interested in art, archaeology, or religious history, this price reflects a meaningful, intimate experience that goes beyond typical sightseeing.
Practical Tips
- Arrive 15 minutes early at the basilica’s portico to ensure smooth entry.
- Remember the dress code: shoulders and knees covered—no shorts or sleeveless shirts.
- Bring ID, as it’s required for security checks.
- Be prepared for stairs if you’re doing the underground tour.
- The underground tour is not recommended for children under 7 or those with mobility issues.
Who Should Book This Tour?

This experience is perfect for art lovers, history enthusiasts, and spiritual travelers who want a deeper, more private look at one of Rome’s most important basilicas. The tour’s focus on exclusive areas and expert commentary makes it ideal for those craving context and authenticity. If panoramic views and archaeological gems excite you, this tour hits all the right notes.
However, it’s less suitable for travelers with mobility constraints or those looking for a quick, casual visit. Given the stairs and quiet spaces, it’s best suited for visitors comfortable with walking and some physical activity.
