Beneath the streets and cobbled pathways of the City of London lies a wealth of Roman history surviving 2000 years of building, fire and bombings. Lower Thames Street is home to one of Roman London's most fascinating remains. Enter an apparently unremarkable office building, meet your City Guide and descend underneath the streets to explore the site of the Billingsgate Roman Bathhouse. It was discovered in 1848, but actually dates to the late second century and is now open to visitors for a limited period. Come and explore this extraordinary glimpse into ancient City life on this guided tour lasting just under an hour.

Please note that tickets (include a booking fee) must be booked in advance and the only access to the site is via a staircase.
