RD Laing, the radical psychiatrist opened a centre in London in 1965 that aimed to revolutionise the treatment of mental illness. Kingsley Hall soon became notorious for drugs, wild parties, therapy and mystics. Almost five decades on, photographer Dominic Harris has tracked down former residents, visited them, photographed them and interviewed them. The result is a self-published photography book, The Residents, which includes Harris’s intimate portraits, as well as personal testimonies of those who were there.
