Dive beneath the waves to visit this underwater museum in Greece

Emerging from the crystal-clear turquoise waters of the Aegean Sea, Hans-Juergen Fercher has just returned from his fourth dive to where mounds of 2,500-year-old wine pots mark the site of an ancient shipwreck – and Greece’s first underwater museum.

“This is a combination of diving and archaeological diving. It’s diving into history,” says the 48-year-old psychiatrist after pulling himself onto the deck of the Triton dive boat.
