I FINALLY made it over to the Mithraeum! I’ve been trying to get here for a few years but just never had enough time on layovers. This is such a fantastic space and a fantasic way to allow visitors to learn & engage with an archaeological site. I’m obsessed with the light “walls”. 10/10 highly recommend. #archaeologytiktok #archaeology #london #romanempire #travel

Reviews Summary

Visitors praise the London Mithraeum for its unique blend of ancient history and modern presentation, calling it a 'hidden gem' and a 'fascinating portal'. The immersive experience, free entry, and knowledgeable staff are frequently highlighted as positives. Some note it can get crowded, and the visit is relatively short, but overall, it's considered a worthwhile and engaging historical deep dive.

"A very interesting find! Free to visit. Disabled friendly - (even has a lift!). Such fascinating history; what has been preserved is amazing! Staff are very friendly and knowledgeable regarding the history. The lower level where the immersion show is good to see as you hear the Latin talk/chanting and listen to narration on the cult. This won't take up much of your day but is well worth a visit if you are in London."

Sarah -.

"Quite a unique experience. Not sure how and when it is open normally, as we have visited as part of the Open House Festival for free. It’s not huge, just two rooms - one with a bit about what the mithraeum is and what we know about it, the other is the actual temple (what is left of it) with a short immersive experience of how it would have sounded back then. Wort a visit if you are interested in the Roman history of London."

Anastasia Balandina

"The London Mithraeum was an interesting experience with its well-preserved ruins and informative audio guide. The historical artifacts and layout provide a good glimpse into the ancient Roman temple. However, I was disappointed that it lacked a holographic display as expected—only audio was available. Still worth a visit for history buffs, but it could have been much better with more immersive visuals!"
