Offa's Dyke is a linear earthwork that forms part of the eighth-century frontier structure built under King Offa of Mercia to demarcate the boundary between the English midlands and Wales. This section, located north west of Coxbury Farm in Gloucestershire, survives as a substantial bank and ditch formation characteristic of the dyke's construction across the Welsh border region. The monument dates to the later eighth century and represents one of the most significant territorial engineering projects of the Anglo-Saxon period. The earthwork remains an important archaeological feature for understanding early medieval political geography and the consolidation of Mercian power during the late eighth century.
