Museum/arts/culture
Seven meters below Bloomberg's City headquarters sit the actual archaeological remains of a 3rd-century Roman temple dedicated to the god Mithras, discovered during construction and preserved on its original site. A free, atmospheric light and sound presentation recreates the temple's rituals before visitors view the ruins directly, an experience reviewers consistently call unique and unexpectedly moving for a free attraction. Its strong hidden-gem and culture scores reflect a site that feels like a genuine discovery rather than a typical museum stop, tucked into the middle of the modern financial district. At 40 minutes, it's an efficient, atmospheric detour for anyone interested in Roman London.

What people say
"Fantastic museum, one of the best I've visited for it's facilities and design. Amazing 5 minute light and audio display, followed by free viewing of the ruins, it's reconstruction of the atmosphere of the temple was very impressive. The display and interactive tablets showcasing the artefacts is brilliant and some of the best exhibition information displays I've experienced. Great friendly staff and free, not to miss! Toilet facilities and seating on the lower floor (non on the ground level with artefact unfortunately). Need to book online beforehand but can also turn up (we couldn't navigate the website well and were booked in when we got there by staff)"
