The chapter serves to introduce the first-ever book dedicated to public archaeologies of frontiers and borderlands. We identify the hitherto neglect of this critical field which seeks to explore the heritage, public engagements, popular cultures and politics of frontiers and borderlands past and present. We review the 2019 conference organised by Uiversity of Chester Archaeology students at the Grosvenor Museum, Chester, which inspired this book, and then survey the structure and contents of the collection. We advocate that public archaeologies should seek to incorporate and foreground perspectives ‘from the edge’. By this we mean public archaeology should make frontiers and borderlands – including the people living with them and seeking to traverse them – paramount to future work.
