Northumberland is a county in northeast England on the Scottish border. It borders Cumbria, County Durham, and Tyne and Wear. The county town is Alnwick, and the county council is located in Morpeth. It is the site of the ruins of the Roman fortification Hadrian’s Wall and is the site of several medieval castles due to its positioning at the Scottish border. During the Industrial Revolution, Northumberland was the site of many coal mines which remained in operation before the closures in the 1970s and 80s.
