Offa's Dyke is a linear earthwork of eighth-century date, constructed during the reign of King Offa of Mercia. The section extending approximately 950 yards north and south of Big Oaks in Herefordshire comprises part of this substantial defensive and territorial boundary that once stretched for many miles along the Welsh border. At this location the dyke survives as a substantial bank with an associated ditch, representing the characteristic form of construction employed throughout its length. This particular stretch remains a significant testament to early medieval engineering and the political geography of the Anglo-Saxon kingdom of Mercia.
