Hadrian's Wall remains one of the most iconic elements of Roman frontier infrastructure, with considerable symbolic capital in all kinds of contemporary situations and representations. Whether inspiring the fictional ice wall in Game of Thrones or illustrating debates about English–Scottish relationships in Brexit-era Britain, the Wall has a powerful legacy. In more scholarly circles, the Wall sometimes figures in the literature of the emerging field of Border Studies, too, and in this paper I examine some of these representations, as a prelude to discussing what Border Studies offers to Wall studies within Roman archaeology. While the interdisciplinary nature of Border Studies can mean that Hadrian's Wall is misunderstood when taken out of context, this does not mean that the broader insights of Border Studies have no value to Roman archaeologists in better interpreting the Wall and its place in Roman Britain. To the contrary, the combination of innovative theories of frontiers and borderlands with detailed, nuanced understanding of the Wall communities through time has much to offer the archaeology of Britain in the Roman empire. Indeed, this field has the potential to connect frontier studies better with other dimensions of Roman provincial archaeology than has been typical in our discipline over much of the last half-century.
