Nature has rewarded us with so much treasure and beauty for those who have the eyes to see and the soul to admire it. Walking on the abandoned beaches you can find beautiful seashells- past homes of God creatures, little debris of glass, evidence for the wordly imprint of human civilization and naturally coloured stones. Here is what I found on a beach at the very heart of city of Kavala.
