Cultybraggan lies close to the village of Comrie, in west Perthshire. It was first used as a prisoner of war (PoW) camp during World War II, and then became an Army training area. It later housed a Royal Observer Corps (ROC) nuclear monitoring post, and a Regional Government Headquarters (RGH). The camp ceased to be used by the military in 2004, and now belongs to the Comrie Development Trust, bought through a community right-to-buy option for £350,000 in 2007.
