This claustrophobic image of inmates sharing beds in an overcrowded cell in Pollsmoor Maximum Security Prison formed Mikhael Subotzky’s 2004 thesis project at the University of Cape Town. He visited inmates, getting to know them and teaching them photography. The visits resulted in this project; its title The Four Walls refers to prisoners’ slang for the enclosing facades. In 2005, on South African Independence Day, these photographs were exhibited inside the prison itself, creating a unique experience by transforming a penitentiary into an environment for expression and exploration.
