The sunken city of Baiae, off the western coast of Italy, remained hidden beneath the sea for over 1,700 years. Once a lavish retreat for Roman elites, including Julius Caesar, Nero, and Hadrian, Baiae was known for its luxurious villas and temples. Pliny the Younger lived here, and the city stood as a symbol of Roman opulence. Following the eruption of Mount Vesuvius in 79 AD, Baiae, like Pompeii and Herculaneum, was partly submerged. Rediscovered centuries later, it continues to offer a fascinating glimpse into the grandeur of ancient Rome, preserved beneath the waves.
