Offa's Dyke is a substantial linear earthwork forming part of the famous eighth-century frontier monument constructed under King Offa of Mercia. This section, located on St Briavels Common east of Upfield House in Gloucestershire, comprises a well-preserved bank and ditch that runs broadly north to south across the landscape. The dyke was built in the latter half of the eighth century, probably during the reign of Offa (757–796), and represents one of the most ambitious engineering projects of Anglo-Saxon Britain, designed to demarcate the border between the Mercian kingdom and Welsh territories. At this location the earthwork survives as a prominent archaeological feature, demonstrating the scale and durability of this early medieval military and territorial boundary system.
