London got its start as the Roman city of Londinium in the first century AD. Back then the so-called “mystery religions” were very popular in the Roman Empire. These cults, with their personal connections to the divine and secret rites, gave believers a more personal experience than the giant temples to Jupiter, Mars, and the rest of the standard pantheon. One of the most popular mystery religions was that of Mithras, an eastern deity whose worship appears to have been open only to men, mainly soldiers.
Since Mithraic rites were secret, not much is known about their beliefs, but there are many similarities between Mithraism and Christianity, such as Mithras being born on December 25 to a virgin, and having died and been resurrected for the salvation of mankind. Both faiths practiced baptism and communal meals. The similarities were so numerous that early Christian writers claimed the older religion was invented by the Devil as a cheap imitation of Christianity before Jesus was even born!
Temples to Mithras, called mithraea, have been found all over the Roman Empire, including one in the heart of London. The mithraeum in Roman London was discovered in 1952 and moved 90 meters away and set up on Queen Victoria St. The restoration wasn’t a completely accurate one. One major problem was that it was put on a podium when mithraea were generally underground.
Now the site has been bought by Bloomberg LP, which plans to build its European headquarters there. Bloomberg LP is going to dismantle the temple and put it back in its original location, according to a press release from the Museum of London Archaeology. The temple will be dismantled starting on November 21 and the corporation says the new reconstruction will be much more accurate. There’s no word yet on when this whole project will be completed. Such a large and delicate process will probably take several years.
