Offa's Dyke path's 40th anniversary celebrations

"Events are to be held to celebrate the 40th anniversary of one of Britain's most popular walking trails.

The Offa's Dyke path, which stretches along the England-Wales border from the River Severn to the Irish Sea, was officially opened on 10 July 1971.

A number of activities will take place at the Offa's Dyke Centre in Knighton, Powys."
