Harperley POW Camp 93 is a surviving purpose-built World War II Prisoner of War (PoW) camp built to accommodate up to 1,400 inmates at Fir Tree near Crook, County Durham in the northeast of England. A work camp for low risk PoWs, it was built on a hillside overlooking Weardale and across the valley from Hamsterley Forest. It was built, initially, in 1943 by Italian PoWs to similar plans of other existing Ministry of War Standard Camps of World War II in Britain and was typical of many military installations around the country. It is the main camp for a number of satellite camps, also numbered 93. Nearby Bishop Auckland used Harperley PoWs and was another installation numbered Camp 93.
