Designed by EMA and HLM as a rehabilitative facility. En-suite cells, vocational workshops, music studio, climbing wall, and forest exterior.
Halden Prison (Norwegian: Halden fengsel) is a maximum-security prison in Halden, Norway. It has three main units and has no conventional security devices. The third-largest prison in Norway, it was established in 2010 with a focus on rehabilitation; its design simulates life outside the prison. Among other activities, sports and music are available to the prisoners, who interact with the unarmed staff to create a sense of community. Praised for its humane conditions, Halden Prison has received the Arnstein Arneberg Award for its interior design in 2010 and been the subject of a documentary, but has also received criticism for being too liberal.
