Basiluzzo
Aeolian Islands · Italy
Basiluzzo is an uninhabited basalt stack with some of the richest posidonia seagrass meadows in the southern Tyrrhenian Sea, and its rocky perimeter is scattered with ancient Roman amphorae — evidence of a trade route active more than 2,000 years ago. The combination of archaeological artefacts lying undisturbed on a living posidonia bed is extraordinarily rare, and the site has been studied by marine archaeologists alongside marine biologists. Large grouper, octopuses, and moray eels shelter in the basalt rock while the meadows above teem with juvenile fish and pipefish.
