Offa's Dyke is an 82 mile long earthwork, incorporating a ditch, that stretches along the border between England and Wales. It is thought to have been built for King Offa who was the Anglo-Saxon king of Mercia 757AD-796AD, though recent research suggest part of it may date from the early 5th century, about the time the Romans departed Britain. The dyke varies in depth and width. A long-distance footpath, the Offa's Dyke Path, is 177 miles long and incorporates about 60 miles of the earth work. The photograph shows a deep section near the town of Monmouth with a footbridge inserted to take the path over the dyke.
