This is the church of St Nikolas in the village of Georgioupolis, St Nikolas is the patron Saint of fishermen, it is built on a bed of rock and a walkway of stones brings you out to it, very picturesque.
Jenny could I suggest that you go for a more letterbox image by removing a large portion of the sky, as it is the same shade of blue from top to bottom. I think this would add more emphasis to the narrow strip of land leading out to the church and the people on it.
