London Mithraeum
What Visitors Say
Highly recommended this. I suggest you book tickets in advance to ensure you slot, but we were able to walk in on a Saturday. The actual temple ruins has a light and sound experience, and then you are able to walk around and view it from many angles. There is also a number of audio activities available, which I would recommend to get the full experience. Staff were courteous and helpful. Bathrooms were available, and very clean. There are 2 flights of stairs down to the temple, but there seems to be lift accessibility if necessary.
The booking process is longer than the time you should actually spend on the site. It’s not even possible to see it properly because of the light and misty effect. There isn’t much to see. If you ever been in any other Roman city you certainly have see more interesting pieces. Unless you are a very passionate about the subject. Very passionate.
I prefer not to call it because it’s too small without many artifacts. But I like the way they exhibit the history with modern technologies (sounds, animations etc.) You only need 30-40minutes to finish the tour.
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.
London’s Mithraeum is London’s best kept secret! What an amazing place right in the middle of The City, free to everyone, without the booking hassle of nearby places, totally underrated in its offerings: hidden London Roman history, nicely preserved & presented in a witty “poly-sensory” representation of what the temple could once had been. Closes on Mondays, and for private events, but you can always walk in, and enjoy this magical experience.

Fun Facts
The temple was first found in 1954, briefly rebuilt at street level, then—during Bloomberg’s redevelopment—carefully returned to its original underground position where you see it today.
Excavations here produced Britain’s largest haul of Roman writing tablets—among them the earliest known reference to ‘London’ and some of the earliest handwritten documents found in the city.
Those ‘notepads’ were waxed wooden tablets reused again and again; stylus scratches sometimes survive even when the wax is long gone.
Entry is free—but it’s timed. Book ahead and you’re more likely to catch the full sound-and-light sequence with space to breathe.
The temple stood beside the lost Walbrook stream—a waterlogged ribbon through the Roman city that helped seal and preserve leather, wood and bone for 1,700 years.
