Post some pictures of your city, specially if it's not very well known outside your country. If you are from some universally known city (New York, Paris or something like that) post some pictures of places you think are interesting but overlooked. Valencia, Spain: The city center, I was born and went to school two streets away from these pictures: Ye olde city center; the two remaining city gates from the middle ages. In one of them you can see what the Napoleonic cannons did. Of course the city grew and the gates are no longer in the edges.
