The Devil's Island of Langlütjen: From military fort to torture site!
The eerie history of the islands of Langlütjen I and II, located off the coast of Bremerhaven, has captivated the hearts of locals for more than 150 years. With a total area of 33,000 square meters, the region not only contains military relics, but also dark secrets that date back to the Nazi era. Loud T Online Langlütjen was built between 1869 and 1870 as a strategic defensive structure to prevent enemy attacks. At that time, the Prussian Navy invested in a fortified coastal fort that was equipped with heavy 21-centimeter guns.
The original logistical challenge could not be neglected. A 1.6 kilometer long dam was built to transport building materials, but it was only accessible at low tide. Langlütjen II was finally completed in 1880 and was also equipped with impressive guns of the time, which were only installed in 1914. But after the First World War, the use changed: the guns were dismantled or blown up, and the remnants of the war are still visible today.
From a military fort to a place of horror
From 1933 the island took on a new and dark meaning. The National Socialists used Langlütjen II as a torture site, where numerous prisoners, especially social democrats and communists, were subjected to cruel mistreatment. Loud NWZ Online At least 81 known names of prisoners were documented by January 1934 before they were transferred to the Ochtumsand concentration camp. The place now known as “Devil’s Island” and “Concentration Camp Under the Sea” exposed the abysmal atrocities that took place there. An eyewitness reported in 2020 that the prisoners' screams could be heard all the way to the shore and the island gained an unholy reputation as a place of horror.
The prison was closed on January 25, 1934 due to the high costs and inadequate supply options. Nevertheless, the memory of these dark chapters of history remains alive. Today a memorial plaque commemorates the terrible events and reminds us of the crimes that were committed here. It is important to keep such memories alive so that history does not repeat itself.
