The cell is a replica of a Camp 5 cell. It brings to life the harsh realities of illegal detention to concerned citizens and highlights the human rights violations that Guantanamo symbolizes. The cell includes a steel toilet, florescent lights and a sliding metal door. Detainees reported being held in isolation in similar cells for as long as 23 hours daily. The Guantanamo prison cell replica will be at the Third Street Promenade through Saturday, Sept. 20.
