This 13th-century Byzantine castle is on the south-west coast of Corfu and is the only surviving medieval fortress in the south.
Originally, it was one of the three castles that formed a defensive triangle to defend the island before the Venetian era and was built by a ruler of the Despotate of Epirus. The castle can be seen from the entrance to Gardiki village. On the parapets along the roof you can see traditional Byzantine artworks. You can also walk along the ramparts which have been almost wholly preserved. The castle is an octagon and most of it remains intact. Its structure makes it one of the most imposing architectural remains across the Ionian Islands.
