This museum commemorating the victims of Nazi war crimes is located in what was first a forced labour camp for around 300 Jews brought in to build a Berlin-Łódź highway and then - when numerous defeats on the Eastern front caused work to grind to a halt, and the inmates were sent off to a death camp in Chełmno nad Nerem - a prison camp for Polish intelligentsia, Soviet POWs, German communists, and those accused of conspiring against the Reich. Around 40 000 people are believed to have been imprisoned here in the years 1943-1945, many of whom perished as a result of inhumane living conditions, torture, and executions. The museum itself was built on the foundations of a prison barrack and opened doors to the public in 1979. To get here, take tram 9 from 'Wrocławska' to 'Dębiec PKM' and hop on bus 611, getting off at 'Luboń Unijna'; the journey takes 35 mins.
