The counter-monument 2146 Stones – Monument Against Racism / The Invisible Monument is an intervention carried out in 1993 on the square in Saarbrücken by Jochen Gerz and students from his class at the Hochschule der Künste Saar, in Saarbrücken, Germany. Executed in accordance with Gerz's constant practice of vigilance [1], the work is the result of a period of unrest in German artistic production that questioned the representational art of a post-war generation, as well as the search of those who lived through the events of World War II and the rise and fall of the Berlin Wall, amidst a national effort to evade the memories of the Holocaust.
