The Main Cemetery (Hauptfriedhof) in Krefeld consists of two parts - the old and the new.
The old part, several dozen metres away from the entrance, on the side of Heidek Street, houses a burial and a memorial site devoted to foreign forced labourers. The site contains the graves of 282 male and female forced labourers employed in the numerous industrial plants in the city and 18 concentration camp prisoners who worked in the Thyssen foundry. The labourers and prisoners died as a result of malnutrition, disease, brutal treatment and air raids. Among the victims were almost 50 Polish citizens most of whom came from the Eastern Borderlands.
In the new part of the cemetery, there is a memorial site commemorating the German political prisoners who were killed in various concentration camps.
