In 2020, the Association of the Jewish Historical Institute in Poland joined the project and was tasked with raising funds and coordinating the construction of the memorial. Backed by more than 40 donors from Poland and around the world, it was possible to raise the necessary funds for the construction of the memorial.
On 19 April 2021, the Ringelblum Archive Memorial was erected at No. 68, currently 28 Nowolipki Street. It consists of three parts - a visible glass cube with a replicated fragment of 19-year-old David Graber's testament, an underground concrete chamber symbolising the cellar where the Archive was hidden, and a narrow black shaft that runs deep into the ground. The path to the memorial is marked by plaques with a quote from David Graber's testament and information about the history of the Oneg Shabbat group.
The efforts of the Association of the Jewish Historical Institute of Poland do not end with the unveiling of the memorial in honour of the Oneg Shabbat heroes who gave their lives to ensure the truth about the Warsaw Ghetto lives on after the war. In April 2021, the association finished constructing a modern repository at the Jewish Historical Institute, where the Archive is stored. Plans are also in place to build a special display case for objects found in the historical layer of Muranów during the construction of the memorial - cutlery, bottles, pottery fragments.
Similarly, on 19 April, the foundation stone was laid for the construction of a symbolic grave for members of the Oneg Shabbat group at the Jewish cemetery on Okopowa Street, Warsaw. We do not know the burial site of most members of the group. Thanks to the symbolic tombstone designed by Natalia Romik, PhD, we pay tribute to the Ringelblum Archive heroes.
"We and future generations must remember these people. It is our absolute obligation". - said Piotr Wiślicki, Chairman of the Board of the Association of the Jewish Historical Institute in Poland, in the film summing up the memorial project.
