Seavenshale, Sewing Shields
Seven Shields was sir Walter Scott’s choice for the name of this, another site beneath which Arthur and his knights are said to lie sleeping. It is in Northumberland, on or almost on the Wall, apparently on the northernside; Seven Shields is perhaps ten miles west and slightly north of Hexham on the river Tyne.
