But that's not what @ghaff was saying. They said: > to say Hadrian's Wall was in at least partly in Scotland at one point isn't necessarily wrong Cumbria, which contains the western end of the wall, was part of Scotland at the time of the Domesday Book (1086), and wasn't incorporated into England until some years later. So there was a period of time when part of Hadrian's Wall was, in fact, in Scotland.
