One of the most recognisable images of the Warsaw Ghetto is that of the footbridge constructed over ul. Chłodna to connect the large and small ghettos. To commemorate that spot is one of Warsaw’s newest memorials: a pair of metal poles connected via optical fibres which, after the sun sets, project the shape of the footbridge over the road via light. Designed by Tomasz de Tusch-Lec and installed in September 2011, the memorial also has viewing windows inside the poles where visitors can flip through images of life in the Warsaw Ghetto. By now you’ve also probably noticed the pavement outline that symbolises the ghetto’s borders, which can be found on the sidewalk as you tromp down ul. Chłodna.
