Ulrike Guérin, UNESCO attorney responsible for the 2001 Convention on the Protection of the Underwater Cultural Heritage, says the museum could change the way we look at underwater heritages.

“It’s difficult, because you can’t go there, and it’s a real issue to see that authentic heritage without having to take it out and dry it up,” says Guerin. “You can never show all of Alexandria—it’s huge—but parts of it are mind-changing.”
