A cross and plaques with the names of former concentration camp prisoners who died in captivity can be seen at a mass grave at the "Langenstein-Zwieberge Concentration Camp Memorial" on November 7, 2024 near Halberstadt, eastern Germany. During the construction of a tunnel system in which warplanes were to be built in the last months of World War II, in the subcamp (Codename ‘Malachite’) of the Buchenwald concentration camp almost 2.000 men died.
