A child's Imression

Recently my son and his friend (both 10 years old) in the process of growing up have started testing the waters slightly away from parental supervision. They asked to wonder alone in a couple of streets in the Nafplion centre (near Syntagma Square). I have accepted and asked the boys to take a camera with them, and take pictures of what they though was important.
They came back with these photos which tell a lot.
