The 8th century Offa's Dyke runs to the west of the village and marked the frontier of the Mercian kingdom. Even today, a lengthy section of the dyke to the southwest of the village forms the English border with Wales. An Anglo-Saxon fort, built in 915 by Ethelfleda, Lady of the Mercians, was located just outside the village on what is now the Montgomery Road. The field that the earthworks are in has long been called Castle Field or King's Orchard.
