Lager Borkum was a labour camp on Alderney, in the Channel Islands, named after the East Frisian Island of Borkum.
The Germans built four camps, two of which became concentration camps on the island, subcamps of the Neuengamme concentration camp (located in Hamburg, Germany). Each camp was named after one of the Frisian Islands: Lager Norderney located at Saye, Lager Borkum at Platte Saline, Lager Sylt near the old telegraph tower at La Foulère and Lager Helgoland, situated in the northwest corner of the island. Over 700 workers died in the Alderney camps (out of a total inmate population of about 6,000) and in ships moving them to and from the Island.
