Some Forest of Dean History.
A Goodly Heritage.
For one hundred and sixty years the greatest English kingdom was the central one of Mercia. Its famous king - Offa - weary of the constant battles with the Britons over the border, began, in 784 A.D., the building of his great dyke, which finally separated Wales from England. The Britons became the Welsh - and the Dean at last became English. This mighty earthwork stretched from the Sedbury cliffs to the Dee - a distance of well over eighty miles.
