This map shows an area c. 100 miles north-south and 120 miles east-west of northern England and the Scottish borders. The border is marked by the heavier dotted line going roughly south west from Berwick-upon-Tweed (at the top of the east coast) down to Gretna (on the west) . I am creating "hot spot" links on the map: look for Newcastle, Hadrian's Wall and the Lake District now.
