The concept of the border as a metaphor has been widely exploited across the Arts and Humanities and a body of Border Theory has been developed, critiqued and "rethought". It is remarkable that this body of theory has largely been ignored by archaeologists, who have instead preferred to examine social and cultural boundaries, frontiers, marginality and ethnicity. This book, which grew out of a session at TAG in 2008, explores some of the possibilities offered by the study of borders from an archaeological point of view and presents new perspectives on borders, both metaphorical and geographical, from locations as diverse as Somerset and China, from the Neolithic to the Cold War.
