Where: Billingsgate Roman House & Baths
It's a tad ironic that London's best Roman remains are underneath the concrete jungle that is the financial district.
Accessible only by guided tour, you enter an office building like any other in the Square Mile before going underground to see a house, bathhouse and courtyard dating back to the second century BC, yet only discovered in 1848. Guides are archaeologists who give an insight into what daily life was like in Roman-era Britain, making this a must for fans of Roman history.
