Offa's Dyke is a linear earthwork of eighth-century date, built under the direction of King Offa of Mercia to define the border between his kingdom and Wales. The section on St Briavels Common, situated 220 metres east of Upfield House, survives as a substantial bank and ditch, representing one of the most impressive stretches of this celebrated frontier monument. The dyke at this location demonstrates the engineering effort invested in its construction and maintenance, with the earthwork running broadly north-south across the common. As a scheduled ancient monument, this section remains an important testimony to Anglo-Saxon territorial control and early medieval political boundaries in the Welsh borderland.
