Today's Offa's Dyke: Heritage interpretation for Britain's longest linear monument

How is Offa's Dyke interpreted for visitors and locals in the contemporary landscape? The article considers the present-day heritage interpretation of Britain's longest linear monument: the early medieval Mercian frontier work of Offa's Dyke. I survey and evaluate panels, plaques and signs that follow the course of the surviving early medieval linear earthwork from Sedbury in Gloucestershire, north to Treuddyn in Flintshire, and along stretches away from the surviving earthwork and north to Prestatyn, Denbighshire along the line of the Offa's Dyke Path National Trail. Critiquing for the overarching narratives and envisionings of Offa's Dyke the first time, I identify how anachronistic ethnonationalist narratives pervade its interpretation: pertaining to the origins of both England and the English, and Wales and the Welsh. As such, the article provides a baseline for further research into the contemporary archaeology and heritage of Offa's Dyke and affords insights of application to other ancient linear monuments in today's world. I conclude with reflections and recommendations for future heritage interpretation of the monument in relation to the national trail, the border and borderlands identities.
