Engineers working on the Thameslink upgrade close to London Bridge Station have discovered what is believed to be the most extensive Roman find south of the Thames.
The remains of the bath house were unearthed on the corner of London Bridge Street and Borough High Street at a site that is earmarked for a new office block.
Specialist archaeologists from Oxford Archaeology and Pre-Construct Archaeology have been commissioned by Network Rail to excavate the buildings, which include a range of rooms with a cold plunge bath and hot rooms with under floor heating.
“This is a significant find and offers a further insight into London’s long history,” said Network Rail archaeologist Chris Place. “In Roman times the main settlement was on the north bank of the River Thames and was connected to the settlement at Southwark by the first London Bridge. Much archaeological work has been done in Southwark over the years, but we were still surprised to discover ruin of this nature and size.”
Network Rail has said that it is currently working with the London Borough of Southwark to look at the options for preserving the remains below the new building.
