Llananno Royal Observer Corps Monitoring Post is a Cold War-era observation post located in Radnorshire, Wales, constructed as part of the nationwide network of monitoring stations established by the Royal Observer Corps from the 1950s onwards. The post dates to the post-1945 period and represents the civil defence infrastructure developed during the height of the Cold War to detect and report nuclear explosions and radioactive fallout. Built to standardised designs, such posts typically comprised a small underground or partially buried concrete structure equipped with instruments for monitoring nuclear radiation and atmospheric conditions. The Llananno post survives as a material record of mid-twentieth-century British civil defence strategy and the Royal Observer Corps's role in national security during the nuclear age.
