"Petalas Island is the largest privately owned Greek island . Situated in the Ionian Sea, this exclusive haven boasts a vast expanse of 5,400,000 square meters, adorned with 4,000 olive trees and surrounded by crystal-clear blue waters.

Some, including William Martin Leake, have suggested that Petalas is the site of ancient Dulichium, from which 40 ships sailed to Troy in the Iliad. However, Strabo and most modern authors have identified Dulichium as Makri, a nearby island in the Echinades.
