This book draws together the work of a new community of scholars with a growing interest in carceral geography. It combines work by geographers on mainstream penal establishments where people are incarcerated by the prevailing legal system, with geographers recent work on migrant detention centres, where irregular migrants and refused asylum seekers are detained ostensibly pending decisions on admittance or repatriation. This book presents a timely addition to emergent interdisciplinary scholarship that will prompt dialogue among those working in geography, criminology and prison sociology.
