Embed­ded into the cob­ble­stones of Europe are Stolper­steine — stum­bling stones. Care­ful­ly hand-chis­eled with names and dates, these small, brass plaques make up the largest mon­u­ment to the Holo­caust in the world. Today, you can find over 100,000 stones across Europe. The Stum­bling Stones Project was begun by artist Gunter Dem­nig as a way to remem­ber that each vic­tim of the Holo­caust had a life that was ter­ri­bly and trag­i­cal­ly stolen. Each memo­r­i­al plaque is placed out­side the last vol­un­tary address of the per­son, the homes from which they were arrest­ed, and often tak­en to con­cen­tra­tion camps. Not all were Jew­ish, some were per­se­cut­ed for being Romani, dis­abled, or queer, and not all shared the same fate. These sto­ries include that of a resis­tance fight­er, an art con­ser­va­tor, an Olympian, and the young Anne Frank. Take a jour­ney around Europe to learn their stories.
