The Border Between the 'Two Englands'. In Great Britain as in the US, two cultural sub-nations identify themselves (and the other) as North and South. There is a place used as shorthand for describing the divide, with the rougher, poorer North and wealthier, middle-to-upper-class South referring to each other as ‘on the other side of the Watford Gap’.
Offa's Dyke Path is one of twelve designated National Trails. With Hadrians Wall It is the only national trail to follow a man-made feature. Built by Offa, King of Mercia in 757 to 796 AD the dyke formed the boundary between England & Wales, running 182 miles from Prestatyn in the north to Sedbury, near Chepstow in the south. Men from the border country along the Mercian (English) side all had to contribute: they could send food or they could build 128cm of dyke.
