Pul E Charkhi Prison, on the eastern outskirts of Kabul, is a place you don’t want to be. Once a notorious dungeon during the Soviet occupation, the prison emerged as one of the principal jails for Taliban prisoners captured by the United States.

The State Department attempted to renovate the prison, but it’s still monumentally terrible. Corruption involving the contractors is the chief culprit for the prison’s problems, according to a recent report from the Special Inspector General for Afghanistan Reconstruction—a congressionally-mandated watchdog agency. Worse, graft became such a problem, the department halted work in 2010.

The result is a prison that has improved in some areas, but remains overcrowded and lacking basic infrastructure.
