Walking on an ancient wall. This is Hardian’s Wall and the only section you are allowed to walk on. Built by Romans nearly 2000 years ago to protect from the wild peoples of the north and very much an inspiration for The Wall in Game of Thrones. And yes, driving towards the north in England and seeing signs for The North and knowing that the wall is there did remind Ramin very much, all the time, of Game of Thrones.
