If you’re someone who loves peeling back layers of history while soaking in breathtaking architecture, this private tour of St Paul’s Cathedral and the Mithraeum could be just the ticket. It’s a thoughtfully curated experience that combines two of London’s most fascinating sites—one famous and well-toured, the other tucked away beneath the city streets, almost secret.
What really draws us in is the chance to explore the Roman temple of Mithras—a rarely seen glimpse into ancient rituals—and then switch gears to marvel at the grandeur of St Paul’s Cathedral, with its stunning dome and intricate carvings. Plus, this is a private experience, which means more personalized attention and a chance to ask all those curious questions you might have.
But, of course, it’s not all perfect. The tour involves a fair bit of walking, so comfortable shoes are a must, and it’s not suitable for those with mobility issues or wheelchair users. Still, for those who enjoy a blend of history, architecture, and unique sights, this walk through London’s layered past is a solid pick.
If you love uncovering stories behind historic sites or are just eager to see two very different sides of London’s past, this tour suits travelers looking for a more intimate and in-depth experience. Whether you’re a history buff, architecture enthusiast, or just curious about London’s underground secrets, you’re likely to find this tour rewarding.

A Closer Look at the Tour Experience

Visiting the Roman Mithraeum—A Hidden Treasure Beneath the City
You start your journey at the London Mithraeum, situated beneath the Bloomberg building. It’s a bit like stepping into a secret world—an ancient Roman temple that was buried for centuries before being thoughtfully excavated and restored for visitors. The guide will lead you through the dark, atmospheric space where you’ll see the famous image of Mithras slaying a bull, surrounded by stars that hint at the cult’s mystic rituals.
What makes this stop particularly interesting is the way the guide explains how the Mithras cult and early Christianity shared themes like light versus darkness, sacrifice, and rebirth. The cult was practiced in secret, much like early Christian communities, so understanding their rituals and beliefs helps connect these ancient dots.
Reviewers consistently mention that the guide’s knowledge makes the visit special. One said, “We loved the way the guide explained the rituals and beliefs—it really made the ancient world come alive.” It’s a space that offers a glimpse into a side of Roman religion that’s often overlooked in broader history tours.
Walking Along Watling Street—An Ancient Roman Path
After exploring the Mithraeum, you’ll walk along Watling Street, one of London’s ancient Roman roads. This stretch offers a tangible link to the city’s Roman past, as you follow in the footsteps of thousands of years of history. It’s a brief walk but meaningful, connecting the underground Roman world with the surface history you’ll encounter at St Paul’s.
Entering the Magnificent St Paul’s Cathedral
Arriving at St Paul’s Cathedral, the scene shifts to one of Christian faith and imperial power. The first thing you’ll notice is the massive dome, designed to lift your gaze heavenward and make a statement of grandeur. As you step inside, the scale is immediately apparent—the nave stretches far and wide, and the detailed carvings in the stonework reveal symbols of power like laurel leaves, tridents, and initials, blending Roman motifs with Christian symbolism.
The guide will point out these details, explaining their significance. “The carvings tell a story of faith intertwined with authority,” one reviewer notes, emphasizing how the architectural elements tie together Roman imperial influence and Christian messaging.
More Great Tours NearbyExploring the Interior and Crypt
From the high altar adorned with ornate decoration, you’ll move down into the crypt, where some of Britain’s most notable figures are buried, including Sir Christopher Wren, the cathedral’s architect, and J.M.W. Turner, the painter. Walking through this space offers a reflective moment, a chance to connect with the human stories behind the majestic stonework.
Many visitors praise the guide’s storytelling, which makes the history of these figures resonate more deeply. One reviewer remarked, “The crypt was surprisingly moving—it’s like walking through the chapters of London’s history.”
