Archaeologists digging in Reims, France have discovered a monumental ancient Roman complex dating back to the second to third century AD. The Roman megastructure uncovered in Reims was found complete with underfloor heating, a hydraulic network and rare pigments. Experts speculate that it was either the home of a wealthy individual or a public spa complex.

Located in north-eastern France, Reims is home to several UNESCO World Heritage Sites, including the Notre-Dame de Reims cathedral, which was the site of coronations for French kings, and the 4th-century Porte de Mars triumphal arch that was built by the Romans.
