Terme Stufe di Nerone sits on Lake Lucrino near Bacoli, west of Naples, where volcanic thermal water has been used since at least the 2nd century BC. Known to the Romans as the Balneum Silvianae, the springs were part of the lakeside resort area of Baia and were later buried by the 1538 eruption that formed Monte Nuovo. Rediscovered in the 18th century, the site today draws on salso-bromo-iodic water emerging at temperatures reported up to around 80°C, used for treating rheumatic and respiratory conditions.
The springs were known in antiquity as the Balneum Silvianae and formed part of Baia, once the most fashionable seaside resort of the Roman elite, frequented by figures such as Julius Caesar, Pompey and Cicero. The 1538 eruption that formed Monte Nuovo buried the ancient baths, and the springs were rediscovered in the 18th century before the modern spa complex was later established at Lake Lucrino.
In Roman times the springs at Baia had a reputation for treating rheumatism and were also believed to aid female fertility, drawing wealthy bathers to the villas that lined the bay.
