Behind Bars: The World's Toughest Prisons

Sofia Central Prison - a Bulgarian detention center, crumbling foundations and fit for demolition - derelict conditions too much to ask of anyone - even a criminal. Multi-prisoner cells, bunks stacked three stories high as well as a large count of isolation cells where prisoners spend 23 hours a day behind rusty bars, with nothing to do, vegetating their days away. Although the European Union requires 43 square feet space per inmate, prisoners in Sofia Central Prison have on average less than half. Central heating and hot running water are considered a luxury. This jail is a place of violence - inter-prisoner violence is rampant and many reports have emerged describing regular abuse by the prison guards.
