Allegedly Greece's Ministry of Culture and Sports is opening up underwater wreckage sites, mostly ships but some aeroplanes, to divers. Near Kef there's the famous HMS Perseus somewhere between Skala and Zakynthos; the SS Ardena, a passenger steam ship that sank in 1943 after striking a mine in the Argostoli Strait; a Junkers Ju 88 shot down south east of Ithaka during the war and the Carinthia V, a yacht which sank south east of Kef in 1971.
