EDIT: Kyriakos, I was curious about one of the buildings in the main Constantinople picture. In the far right of the city, half way up the screen, there's what looks like a sports pitch with small buildings surrounding it and was wondering what it was. Would you know? I've attached the part of the picture that I mean.
