The Langenstein-Zwieberge was a concentration camp, an under-camp of the Buchenwald concentration camp. More than 7000 prisoners from 23 countries were imprisoned there between April 1944 and April 1945.
The first group of deportees from Buchenwald arrived on 21 April 1944. They were 18, French, and formed the executives of the Kommando future. They were initially placed in an inn of the periphery of Langenstein, then, the convoys following one another, while waiting for the completion of the construction of the camp, in a barn, which still exists, located at the exit of the village. Six convoys arrived, from 26 September 1944 to 18 February 1945.
The construction of the camp was completed in August 1944 with the electrified enclosure; 7 blocks plus the appendices (Revier, kitchen, etc.) the inn and the barn replaced. When manpower reached 5,100 prisoners, in February 1945, there were 18 blocks.
Manpower decreased then (4,400 people at the beginning of April 1945), the number of deaths exceeded the number of the newcomers by far.
In the week from 19 to 25 March 1945, on 1308 dead deducted for Buchenwald and its Kommandos, Langenstein-Zwieberge had the unhappy privilege to arrive at the head, with 234 dead, in front of Ohrdruf (207) and Leau (69).
As of the first days of their arrival, the deportees started to dig galleries in the still virgin site of the hills of Thekenberge. In ten months of terrible sufferings, the prisoners completed nearly 10 km of galleries, of a surface of 60.000 m². Some were enough vast to accommodate trains of coaches. Some had cost a death per meter of projection. Life expectancy for prisoners was six weeks.
