Thermes de Cluny

Adjoining the medieval mansion that houses the Cluny museum, these are the substantial ruins of a Gallo-Roman public bath complex from the ancient city of Lutetia. The soaring vaulted frigidarium, or cold room, survives largely intact, its stone arches rising to a considerable height and preserving fragments of decoration. Built around the second or third century, the baths served the Roman settlement on the Left Bank. Integrated into the museum, the ruins reveal the city's classical origins beneath the Latin Quarter.
