Offa's Dyke: Plas Power Section is a linear earthwork forming part of the extensive eighth-century defensive frontier constructed under King Offa of Mercia. This section of the dyke, located in Denbighshire, comprises a substantial bank and ditch arrangement typical of the monument's construction along the Welsh-English border. The earthwork dates to the Early Medieval period, specifically the later eighth century, and represents a significant engineering undertaking intended to demarcate and control territorial boundaries. The Plas Power section remains an important archaeological witness to early medieval political authority and landscape management in the region.
