Cobra Mist explores the relationship between the coastal landscape of Orford Ness and its traces of military history, particularly the extraordinary ruined architecture of experimental radar and the Atomic Weapons Research Establishment. Still under the official secrets act, much of what took place on the Ness will only be revealed over time. Military buildings have been left to the elements to deteriorate, creating a tension between the time it will take for their secrets to come out and for the buildings to disappear.
