Linear monuments offer special challenges in the context of the public archaeology of frontiers and borderlands. This chapter tackles the interpretive neglect of Britain's second-longest early medieval earthwork, Wat's Dyke, showing how its sparse and sporadic archaeological attention is reflected in poor and out-dated public archaeology and heritage interpretation. I evaluate the current media and mechanisms by which various publics -including global digital audiences, visitors to the Anglo-Welsh borderlands through which the monument runs, and local communities living in the Dyke's environs in Flintshire, Wrexham and Shropshire -can access, experience and learn about Wat's Dyke. Having identified how Wat's Dyke is fragmented and obscure in the landscape despite its monumental presence, and how its digital resources are inadequate, I then propose new avenues for developing innovative interpretations of Wat's Dyke for both existing and new audiences which aim to provide upto-date and engaging resources and connect the monument to the rich cultural landscapes, past and present, through which it runs. I argue these recommendations provide the basis for both enhancing awareness and knowledge. I also argue they provide a more robust resources for current and future generations of research and public engagement. I also suggest they serve to combat the risk of pseudo-archaeological narratives and extremist political appropriations of Wat's Dyke.
