The German Organisation Todt (OT) built four labour camps in Alderney to house workers for the planned fortifications.
the control of Lager Norderney changed from March 1943 to June 1944 when it was run by the Schutzstaffel - SS-Baubrigade and Lager Norderney became a subcamp of the Neuengamme concentration camp (located in Hamburg, Germany).
Norderney camp housed European (mostly Russian and other Eastern but including Spaniard) enforced labourers.
Lager Borkum was used for German technicians and volunteers from different countries of Europe.
Close by is a tunnel from the camp to the beach, which is it is claimed was used by the Nazis as a shelter, or possibly as a killing site.
