The Best Hotel Spas in Rome

"Built between 212 and 216 AD on Aventino, the small Aventine Hill, the Terme di Caracalla are one of the largest and best-preserved bath complexes from Antiquity. Located close to the Appian Way, they were supplied by the Aqua Antoniniana, a special connection to the almost 100km-long Aqua Marcia, the third aqueduct in Ancient Rome. The rectangular architecture encompassed a caldarium, a tepidarium, a frigidarium, and a natatio, with rooms arranged symmetrically around the gymnasiums. In summer, the Baths of Caracalla host open-air performances of the Teatro dell'Opera, ballets, and concerts, the scenography of which is extraordinary." - The MICHELIN Guide
