Each Alderney camp was named after one of the Frisian Islands: Lager Norderney located at Saye, Lager Helgoland at Platte Saline, Lager Sylt near the old telegraph tower at La Foulère and Lager Borkum, situated near the Impot.
The Borkum and Helgoland camps were "volunteer" (Hilfswillige) labour camps[REF] and the labourers in those camps were treated harshly but better than the inmates at the Sylt and Norderney camps and were paid for work done.
