Offa’s Dyke, a protected UNESCO World Heritage Site in Wales, was damaged in August when someone with a bulldozer carved out a 50-yard section and used the dirt to fill in a road nearby. It is a criminal offense to disrupt or damage protected monuments, and the authorities are investigating.
A popular walking trail for visitors, the 1,200-year-old monument is a long earthwork stretching about 80 miles from the Wye Valley to Wrexham. The dike is thought to have been built in the eighth century by King Offa of Mercia.
