Due to its strategic position, the shores of Porto Palermo have been utilized for defensive purposes from antiquity to World War II. The well preserved castle was built in the early 19th century by
Ali Pasha of Tepelena. It is unlikely that a Venetian or Ottoman fortification stood there before. An inscription above the entrance says that the castle was built in 1804 by French engineers for Ali Pasha. He was concerned about the open coastal flank of his
pashalik and this was among a number of sea fortresses that he built.
William Martin Leake visited the fort and noted that the garrison consisted of 10 men with two four-pounders.
François Pouqueville in 1806 reports, "The tower or fort stands on the southern point of the entrance, connected with the continent by a low narrow isthmus. It consists of a square with bastions, having a few guns, of no service either to command the entrance or to protect the shipping at anchor. Near it are some warehouses, a custom-house, and a Greek church."
