Stolpersteine are memorial stones that commemorate people who were persecuted, deported and murdered under National Socialism. In Salder and Engelnstedt, Stolpersteine commemorate the fates of the Kleeblatt and Traube families.

The Stolperstein are brass plaques embedded in the ground with the names and dates of people who were persecuted, arrested, tortured, disenfranchised, forced to flee or commit suicide or murdered during the National Socialist era. The stones commemorate all victims of National Socialism at their last freely chosen place of residence.

In 2020, a stumbling stone initiative was founded within the city history working group, which researched the fate of the Kleeblatt family from Salder.

On November 12, 2021, seven Stolpersteine were laid in Salder for the first time in memory of the Jewish Kleeblatt family. The Stolpersteine at Gänsebleek 13 commemorate the family, who ran a textile business until they were forced to leave their home due to massive hostility and physical attacks.

On September 27, 2023, five Stolpersteine were laid in Engelnstedt in memory of the Traube family. The family was ostracized and disenfranchised under National Socialism because of their Jewish ancestors. They lived in Engelnstedt until their forced expropriation in 1943 and ran their own farm at Auf der Graube 17. Father Walter Traube died after his arrest in the Auschwitz concentration camp.

The Stolpersteine are a project by artist Gunter Demnig, who took part in the first laying. Gunter Demnig's Stolpersteine are considered the world's largest decentralized memorial.

With the stones in front of the houses, the memory of the people who once lived here is kept alive. The stones are inscribed with the words: HERE LIVED... One stone. A name. One person.

The history of the Kleeblatt family and the Traube family was the subject of a brochure published by the town history working group, which is available from the working group.
