Monument to the Victims of Nazi Military Justice

The Monument to the Victims of Nazi Military Justice is located at Appellhofplatz in the immediate vicinity of three historically relevant buildings: the former armory (today a building belonging to the Kölnisches Stadtmuseum); the EL-DE-Haus, which was once home to a Gestapo torture chamber; and the courthouse, where over one-hundred people were sentenced to death by the Nazis.
The monument looks like a pergola at first glance. Extending all the way to the nearby U-Bahn entrance, its roof is made out of a series of colored aluminum letters that form a written memorial. This “chain text” refers to the chain reactions that arise from our actions. Just as the viewer can catch a glimpse of the sky in the colored net of letters, our personal thoughts and actions also never remain isolated, as there are always consequences for the network that forms our society.
The monument was inaugurated on September 1, 2009, the 70th anniversary of the German invasion of Poland.
A translation of the inscription on the Pergola is as follows: “Pay tribute to the soldiers who refused to shoot the soldiers who refused to kill the people who refused to torture the people who refused to denounce the people who refused to brutalize the people who refused to discriminate against the people who refused to laugh at the people who showed moral courage when the majority remained silent and followed.”
