Baiae (; ) was an ancient Roman town situated on the northwest shore of the Gulf of Naples and now in the "comune" of Bacoli. It was a fashionable resort for centuries in antiquity, particularly towards the end of the Roman Republic, when it was reckoned as superior to Capri, Pompeii, and Herculaneum by wealthy Romans, who built villas here from 100 BC to AD 500. It was notorious for its hedonistic offerings and the attendant rumours of corruption and scandal.
