One of my many days out exploring London, I was looking for free things to do in London and you get the usual museums and art galleries but when I come across The London Mithraeum, I'd never actually heard of it and was massively intrigued. The London Mithraeum Bloomberg space is situated on the site of their new European headquarters and returns The Roam Temple of Mithras to the locations of its discovery. A much anticipated new cultural hub showing the ancient temple, an amazing selection of artefacts discovered during the recent excavation and loads of art commissions from one of most significant archaeological sites discovered.
