Located in the town of Saintes, the thermal baths of Saint-Saloine are the remains of a Roman spa establishment created in the 1st century AD. Located in an outlying district of the town, like from the amphitheater, the remains classified as Historical Monuments still reveal to visitors sections of the walls of the old caldarium, stones from the Saint-Saloine church, a later building abandoned in the 16th century.
The site, which bears witness to the daily life of the inhabitants of Saintes under Antiquity, also unveiled during archaeological excavations many ancient and medieval sarcophagi, meaning that the place was subsequently transformed into a necropolis.
