The halls of the former prison in Iran's capital now are hushed, befitting the sounds of the museum that it has become. Wax mannequins silently portray the horrific acts of torture that once were carried out within its walls.
Exhibits in the former Anti-Sabotage Joint Committee Prison that was run under Shah Mohammad Reza Pahlavi include a frightened man trapped in a small metal cage as a cigarette-smoking interrogator shouts above him.
As Iran this month marks the 40th anniversary of its Islamic Revolution and the overthrow of the shah, the surviving inmates who suffered torture at the hands of the country's police and dreaded SAVAK intelligence service still bear both visible and hidden scars. Even today, United Nations investigators and rights group say Iran tortures and arbitrarily detains prisoners.
