Signs can be seen on a fence with a signpost to the ‘Reichsstollen’ tunnel of the Langenstein-Zwieberge concentration camp memorial and a warning sign with the inscription ‘No unauthorised access’, 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.
