Ali Pasha's Castle, also known as Kalaja e Ali Pashës, occupies a small island at the mouth of the Vivari Channel near Ksamil, within Butrint National Park. The fortress traces its origins to the late 15th or early 16th century when Venetians constructed it as a strategic stronghold, though Ali Pasha of Tepelenë significantly enhanced its defenses with gun batteries in 1804 and rebuilt it in 1819 with three towers. Visitors can reach the castle by boat from the Butrint archaeological site entrance for approximately 2500 lekë, experiencing both Venetian and Ottoman architectural influences while enjoying panoramic views of the Ionian Sea.
