The Story

What is claimed · what is sourced · what is still disputed

Baiae was where Rome went to misbehave, Caesar, Nero, and Hadrian kept villas on this volcanic shore. Then the bradyseism that built the coast let it down, gently, into the sea. Today the nymphaeum statues stand in four metres of green light and mosaics roll out under a diver's hands. The whole resort is an underwater park: shallow enough to snorkel, rich enough to dive for a week.
