Ten years and 1.5 billion Norwegian kroner ($252 million) in the making, [Halden Fengsel, Norway's newest prison,] is spread over 75 acres (30 hectares) of gently sloping forest in southeastern Norway. The facility boasts amenities like a sound studio, jogging trails and a freestanding two-bedroom house where inmates can host their families during overnight visits. The scent of orange sorbet emanates from the kitchen laboratory" where inmates take cooking courses. "In the Norwegian prison system, there's a focus on human rights and respect," says Are Hoidal, the prison's governor. "We don't see any of this as unusual." Halden ... embodies the guiding principles of the country's penal system: that repressive prisons do not work and that treating prisoners humanely boosts their chances of reintegrating into society. "When they arrive, many of them are in bad shape," Hoidal says, noting that Halden houses drug dealers, murderers and rapists, among others. "We want to build them up, give them confidence through education and work and have them leave as better people." Within two years of their release, 20% of Norway's prisoners end up back in jail. In the U.K. and the U.S., the figure hovers between 50% and 60%.
