When architecture serves as a tool for punishment through confinement and isolation, every design choice affects lives. What is prison architecture? Where do spaces of incarceration from jails to migration camps and beyond materialize? How do their spatial logics haunt our contemporary societies? For the first time, Carceral Architecture offers readers an account of prison design and its effects by centering the voices of people impacted by the correctional system in the United States alongside those of activists, architects, designers, scholars, artists, and students. In so doing, it highlights a much-neglected issue of our time and helps reimagine a society that continues to be marked by the reality of mass incarceration.
