Pictured are all three Sound Mirrors at Lade Pitt, Denge Lydd, Kent.
These are situated on an island behind a caravan park between Greatstone-on-Sea and Lydd-on-Sea. They can be visited on one of the guided tours that take place three or four times a year, as they control the access bridge.
These were built before the WWII, but were rendered obselete within a couple of years as Radar technology arrived.
Thankfully the soldier that was sent out to demolish them, had to go back to his barracks to get some more explosives, and whilst there was given another task, so he never went back to finish off the job.
