Offa's Dyke: Plas Power Section is a linear earthwork forming part of the larger eighth-century frontier work that marked the border between the Anglo-Saxon kingdom of Mercia and the Welsh kingdoms to the west. This stretch, located in Denbighshire, comprises a substantial bank and ditch constructed during the reign of King Offa of Mercia, probably in the latter decades of the eighth century. The dyke at this location demonstrates the considerable engineering effort invested in creating a continuous defensive or demarcation line across the Welsh borderland. The Plas Power section survives as an impressive upstanding monument, preserving the characteristic morphology of Offa's Dyke with its prominent earthen bank and parallel ditch.
