The temple was built in the mid-3rd century and dedicated to Mithras or perhaps jointly to several deities popular among Roman soldiers. Then it was rededicated, probably to Bacchus, in the early fourth century. Found within the temple, where they had been carefully buried at the time of its rededication, were finely detailed third-century white marble likenesses of Minerva, Mercury the guide of the souls of the dead, and the syncretic gods Mithras and Serapis. There were several coarser locally-made clay figurines of Venus, combing her hair1.
The whole site was uprooted and moved down the road to Temple Court, Queen Victoria Street, London EC4, where the remains of the temple foundations have been reassembled for display to the public. However, the site is to be moved again, now back to the original location2.
