During World War II, bordering the South Tyne river and stretching across a mile of Featherstone Park, there was "Camp 18", a POW camp that housed 7000 German Officers after 1945. Some of the remains of the camp are still visible on the grounds of Featherstone Castle. The camp closed its doors on 15 May 1948. The remaining German officers were sent by bus to Haltwhistle, from where they took the train to other clearing camps in Britain, and then they went to Germany. In 1950 the contents of the camp were sold.
