In 2018 Harrie-Jan Metselaars wrote the book 'En toen waren ze weg' (And then they were gone) about the persecution of the Jews in Gennep. Since that year, 22 stumbling stones have been placed throughout the centre, giving a name to the Gennep victims of the Shoah.

 The concrete stones with a brass plate that includes some personal information can be found all over Europe. They are intended as small, individual monuments to the victims of National Socialism: Jews, Sinti and Roma, political prisoners, conscientious objectors, homosexuals, Jehovah's witnesses, and people with mental or physical disabilities. The stones have been embedded in the pavement in front of the victim's original home.
