Nero's Sunken City (S16E04)

A team of archaeologists dives beneath the waves to map the submerged ruins of an ancient Roman resort town—a playground for the wealthy, often called Rome’s version of Las Vegas. Using sonar and underwater cameras, they document sunken temples, mosaic floors, and streets swallowed by the sea. This lost city, once alive with parties, gambling, and luxury villas, now lies silent beneath the Mediterranean. Their work reveals not just a catastrophe of nature, but a vivid snapshot of imperial excess frozen in time.
