Baia, once a thriving Roman town, now lies on the Gulf of Naples' northwest shore. This ancient town, founded on the Cumaean Peninsula in the Phlegraean Fields (an active volcanic area), was a fashionable resort for the Roman aristocracy around 80 BC. Wealthy Romans, including emperors like Julius Caesar, built lavish villas here.

Recent underwater archaeology has revealed fascinating submerged structures in the Baia Submerged Archaeological Park. History comes alive as you explore these protected ruins. Visit Terra Murata, the ancient fortified village with stunning views. Discover the remarkable thermal baths – the Temple of Diana, Temple of Mercury, and Temple of Venus – within the temple complex. While nightlife is subdued, Baiae offers cozy cafes and local eateries serving the traditional Zingara pastry. The allure of Baia even inspired scenes depicted on ancient glass flasks made for visitors throughout the Roman Empire.
