The modern day appearance of Delamere Park is far removed from its past setting as one of the largest displaced persons camps in the North West of England. Delamere House itself and its surrounding parkland had been deserted for nearly a year when in 1939 the Second World War broke when Hitler's troops invaded Poland. In Britain as part of the war effort huge areas of land from several country estates were requisitioned by the War Office in order to build airfields and army camps necessary for the war effort. By 1941 Delamere Park was transformed into a vast army camp consisting of Laing and Nissen huts which housed around 15,000 American troops.
