When conceptual artist Gunter Demnig first conceived the idea of laying Stolpersteine (literal translation: stumbling stones) for Roma, Sinti, and disabled victims of National Socialism in his native Germany, he never imagined his project would grow to become the world's largest decentralized memorial. The Stolpersteine he crafted is, in theory, quite simple: concrete blocks measuring 10x10cm, topped with permanent brass plates that are hand stamped with the names and fates of victims of Hitler's reign of terror. The stones are laid into the pavement in front of the last voluntarily chosen residence of those murdered by the Nazis. They are deeply personal and draw attention to individual tragedies. They have now been placed in 30 countries across Europe and on May 23rd, 2023 we filmed Gunter Demnig laying the 100,000th Stolpersteine.
