Archaeologists report discovering an “incredibly rare” and featured preserved floors and walls Roman mausoleum near London Bridge Station, UK.

Archaeologists discovered big Roman mosaics at the same location last year, which led scientists to believe something much larger might be buried beneath the surface. Excavations conducted by MOLA archaeologists on behalf of Landsec, Transport for London, which owns the site, and Southwark Council have yielded extraordinary results.

Archaeologists say they have unearthed the remains of a Roman mausoleum “with an astonishing level of preservation.”

The Museum of London Archaeology believes the quality of preservation makes it the most intact Roman mausoleum ever to be discovered in Britain.
