The 16th century Genoese castle is both visually attractive, lying on top of a wild island (since the 1940's connected with the mainland) and with a fascinating history. From 1541 and until the middle of the 18th century it was a Christian stronghold in the middle of the Ottoman Empire. Around the castle, a tiny town of 1,200 inhabitants was built. Nothing remains of this now. Unfortunately, most of the inner parts of the castle is in use by the Tunisian military. Only a small section is open, with a tiny museum showing reproductions of mosaics.
