The London Mithraeum, discovered in 1952 under the bombed out ruins of London, is now rebuilt and open to the public to give you a "memorable, powerful and authentic experience."The London Mithraeum was built 1800 years ago by the Romans and dedicated to the god, Mithras. In 1952 a small section of a Roman building was discovered and on the last day of the dig in 1954 its function was confirmed as a temple devoted to the God Mithras. The evidence on that last day was a sculpted head of Mythras. The temple was first built around 240-250AD and was eventually abandoned in about 380AD and is now open to the public in the Bloomberg building. A further excavation took place between 2012-2014 and discovered more than 14 000 artefacts, together with 63 000 pieces of pottery and 3 tonnes of animal bones. This together with the original finds means that this was has become a highly important site in the history of London. Over 400 pieces of writing tablets have been found and this includes the first known reference to London and the earliest hand written document. Some 600 artefacts are on display as well as the temple itself. Several other key finds are on display in the nearby Museum of London. (20 minutes walk)
