Llananno Royal Observer Corps Monitoring Post is a Cold War observation post located in Radnorshire, Wales, dating from the mid-twentieth century. The site represents the civilian defence infrastructure developed by the Royal Observer Corps to monitor radioactive fallout and provide early warning of nuclear attack during the period of heightened tension between the Soviet Union and the Western powers. The post would have comprised a reinforced underground or partially buried structure, typical of ROC monitoring stations constructed across Britain from the 1950s onwards, equipped with instruments for detecting radiation and communications equipment for reporting observations to regional headquarters. Such posts were staffed by trained volunteers who maintained surveillance during peacetime and would have activated in the event of a nuclear emergency, forming a crucial component of Britain's civil defence network during the Cold War era.
