This article addresses questions relating to the 'Frontiers of the Roman Empire World Heritage Site' and seeks to introduce into this initiative some concepts derived from recent writings on contemporary mobilities and bordering, exploring the possibility of creating greater engagement between the two academic fields of 'border studies' and 'Roman Frontier Studies'. By examining the relationship between the Roman Frontiers initiative and the European Union's stated aims of integration and the dissolution of borders, it argues in favour of crossing intellectual borders between the study of the present and the past to promote the value of the Roman frontiers as a means of reflecting on contemporary problems facing Europe. This article considers the potential roles of Roman Frontier Studies in this debate by emphasizing frontiers as places of encounter and transformation.
