Since there are down votes, I will clarify my question do that we do not jump into underground nationalism: I was looking for unique features that make it recognizable. As I mentioned in a comment: the Peru flag is unique, this recognizable for instance. If the map was round then yes, it is recognizable. Does it have any such features? Or is it just recognizable because London is well known, so some stations are too?
