Historic center of Dubrovnik, Croatia with a couple of churches and a clocktower visible with the Adriatic Sea in the background. Dubrovnik is really amazing and I can definitely see why it was chosen as King's Landing but I found it difficult to really enjoy the city because it is so expensive. Western Europe is cheap compared to this place. For example just walking on the city walls costs almost $25. Twenty five dollars just to walk on an old wall! I've been to plenty of old towns with city walls and it is usually free, or at least reasonably priced.
