The Billingsgate Bath House was discovered in 1848 by construction workers during the London Coal exchange. They preserved this excellent Roman find in the basement of the building up until the 1960s where archaelogists were able to further explore the ruins.Billingsgate Bath House dates back as far as 2nd century AD. The house itself consisted of an North and East wing as well as heated flooring and would overlook the River Thames. The Bath House consisted of three different rooms to accomadate temperature: cold, warm, and hot. This was done through use of the Hypocaust system which took heat from the furnace and would spread to first the warm room (tempidarium), then hot (caldarium). Then the Romans would finish off their bath with the cold room (frigidarium) to close their pores. The Billingsgate Bath House was used up until the 5th century, when the Roman military left London and left the city to ruin. Roman Bath, Lower Thames Street, "Know Your London".
