The Łódź Ghetto was more isolated than other ghettos in occupied Poland. It was cordoned off with a fence and watch posts, guarded by armed German policemen, who were allowed to shoot without warning at anyone who would approach the boundary of the ghetto. The houses that had stood along the boundaries of the ghetto were demolished – this way an open space was created to make it impossible to sneak unnoticed. Another aspect of isolation was introducing different currency in the ghetto. Ghetto money was worthless outside its boundaries. Forced labor was only organized within the ghetto area. The part of Łódź, where the ghetto was located didn’t have sewage system – it was therefore impossible to get out to the “Aryan” side through the sewers, as some people did in Krakow or in Warsaw. The only newspaper allowed in the ghetto was the official “Geto Tsaytung”. Its readers learned next to nothing about the world outside the ghetto.
