Haraki's Castle by sandysmith
In Haraki is a medieval castle, overlooking the pretty bay. This is Feraclos castle once used by pirates before the Knights ousted them and then reinforced the castle to use it as a prison. There is a path leading up to the castle ruins but I didn't make it up the hill - I was enjoying my sunbed and swimming far too much - perhaps the next time we visit as from the top of the hill there are good views onto Agathi beach another fine secluded beach.
