Brochure The Stadium presents the tragic history of the City Stadium in Poznań at Dolna Wilda Street. During the Nazi occupation, it was a place where Jews from the Warthegau were imprisoned and forced to perform slave labor in Poznań. German private companies particularly benefited from the stadium inmates' work. The prisoners worked on the construction of highways, railway tracks on the Dębiec-Antoninek route and on shaping the basin of Malta Lake.
