Enrico Gallocchio, an archaeologist, told AFPTV that when we investigate new areas, we remove the sand gently where we think there might be a floor. We then document it and then re-cover it."
"If we don’t, the marine fauna and flora are going to attack the ruins." Gallocchio, who manages the Baiae park, said that the sand protects them.
