The Mithraeum was excavated by William Francis Grimes on Walbrook in London. This has now been repositioned in the basement of Bloomberg Space. Visitors experience the darkness of the space and light levels are increased so that the remains can be seen.
Some of the sculptures are displayed in the nearby Museum of London. They include a relief of Ulpius Silvanus, formerly of the II Augustan legion (based at Caerleon). He appears to have been initiated to the cult at Orange in modern France.
