The Antonine Wall is NORTH of Hadrian's. It is in what is currently Scotland but hopefully will someday be restored to be rightfully part of Northumbria. Lowland Scotland is of course English-speaking (well, sort of) as opposed to the Celtic fringes, and has more in common with Northern England than either have with the Highland Celts or Southerners.

This posting has been brought to you by the Northumbrian Liberation Front...but it is still true. Especially that bit about the Antonine Wall.

Incidentally, it has been argued that the Vallum, or ditch, south of Hadrian's Wall was put there to stop the Geordies stealing the lead from the roofs.
