For the past four decades, a rich scholarship has investigated the emergence of the prison in Europe and North America, mainly the connection between institutional architecture, techniques of social control, and mechanisms of discipline. Prison Architecture and Punishment in Colonial Senegal asks if these connections did exist in colonial Senegal since prisons in Africa had never been the focus of such scholarship. This book addresses three main themes. First, it analyzes prison buildings and their changing architectural forms throughout the colonial period to highlight how the French used prison architecture to control Africans. Second, it describes the connections between the internal layout of prison spaces and punishment to show how the design of prisons expressed the notions of punishment and reforms. The book also undertakes a critical assessment of inmates’ agency in reshaping the world of prisons in colonial Senegal. Finally, it discusses the legacy of colonial prisons in independent Senegal. By providing a comprehensive history of prison architecture in Senegal, the book helps insert Africa into a more global history by offering a uniquely comparative study of colonialism, architecture, and punishment.
