Despite whatever parallels you might see between the British Monarchy and that of the Seven Kingdoms, Queen Elizabeth II wants no part of it. As this photo clearly shows, the royal spurned an opportunity to sit on the Iron Throne while taking a tour of the Game of Thrones set in Belfast today. Maybe she declined because she didn’t want to offend the former GoT queen Cersei Lannister (Lena Headey) lurking smilingly in the background? Or maybe because the Queen didn’t want to be jabbed by the sharp blades that the throne is made out of? Or maybe she just has some goddamn sense: Royals in Westeros don’t tend to rule for very long, whereas she's already reigned over England for 62 years and change, longer even than Jaehaerys I Targaryen, the Conciliator.
Update: Here's a video.
