Built as an early warning device for aircraft the three concrete “listening ears” at Denge on Dungeness are the best examples of this technology and are Grade 1 listed as Ancient Monuments. They were effective, but the development of faster aircraft made them redundant, as an aircraft would be within sight by the time it had been located.
